Ten male albino rats were trained In a brightness discrimination problem where they were reQuired to choose a sttmulus value of 0.053 ft/cd over one of 0.012 ft/cd. Pairs were matched accordlng to the number of trials requtred to reach a criterion of 18/20 correct responses then randomly assigned to one of two grouos for testing In transposition. Both groups were tested on the orlgtnally positive stimulus and a brighter one: 1.25 ft/cd for Group 8-C and 5.38 ft/cd for Group 8-D. By testing...
Show moreTen male albino rats were trained In a brightness discrimination problem where they were reQuired to choose a sttmulus value of 0.053 ft/cd over one of 0.012 ft/cd. Pairs were matched accordlng to the number of trials requtred to reach a criterion of 18/20 correct responses then randomly assigned to one of two grouos for testing In transposition. Both groups were tested on the orlgtnally positive stimulus and a brighter one: 1.25 ft/cd for Group 8-C and 5.38 ft/cd for Group 8-D. By testing for transposttlon wtth non-reinforced trials, contrary to the usual method, a tendency toward converging measures of transposltton was achteved. Transposition for Group 8-D, In the situation most dissimilar to training, was greater than for 8-C. These results were discussed from relational or Gestalt, Spence model, and Adaptation Level positions and It was shown that the results are contrary to traditional Gestalt predictions. It was oredlcted that, according to underlying assumptions of the Spence model, with continued non-reinforced trials, per cent of transposition for both groups would decrease until a chance level of responding was reached. That this did not occur cannot be explained by the Spence model. Because the variability was too great with such a small N, these results did not reach the .05 level of probability.

Show moreThis thesis examined the possibility of meaningful associations between children's attachment styles in middle childhood and children's perceptions of the parent. Participants were 199 students (94 males, 105 females) in grades three through eight (mean age = 11.03 years) from a Florida university school. The children were administered self-report measures and peer-report nomination measures. Five attachment coping strategies (preoccupied, indecisive, avoidant, coercive, and caregiving) and four aspects of perceived maternal behavior (reliable support, overprotection, harassment, and fear induction) were assessed and numerous and meaningful associations were found. For example, perceived maternal overprotection was positively associated with preoccupied coping. Significant associations were also found between our avoidant, coercive, indecisive, and caregiving coping measures and perceived maternal reliable support, harassment, and fear induction. Our numerous and significant findings lend further support for the usefulness and value of our concurrent correlational self-report measures and to justify future longitudinal research to compare alternative models.

As cuckoldry is potentially so reproductively costly, men may have evolved anti-cuckoldry psychological adaptations. Sexual coercion has been hypothesized as one class of anti-cuckoldry behaviors. By sexually coercing an intimate partner, a man may reduce the risk of cuckoldry by placing his sperm in competition with a rival male's spenn, should his partner have been sexually unfaithful. I will present three studies that investigate the role of female infidelity, an assessment of risk of spenn competition and subsequent cuckoldry, in predicting male sexual coercion in the context of an intimate relationship.

Show moreConflicts between groups are affected by myriad historical and situational factors. Yet people are rarely overwhelmed by this complexity and are able to adopt a coherent depiction of the conflict, often with an unequivocal allocation of blame to one group. A person's final judgment tells only a fraction of the story. To uncover the whole story, numerous factors must be considered. Two such factors are whether the person harbors implicit prejudice toward an involved group and whether the way in which relevant information is presented will allow for the emergence of perspective-taking and provide insight into the conflict that will aid third-party observes in making a coherent end judgment. This research explored the role of anti-Muslim prejudice and perspectivetaking in allocating blame for an ambiguous conflict between two groups that differed only on the dimension of religion (Muslim vs. Christian). Participants completed two measures of prejudice-an anti-Muslim Implicit Association Test and an explicit antiMuslim prejudice questionnaire. Participants then viewed one of two versions of a filmed conflict scene. While both films were identical in content, the order of their contents was reversed (conflict first vs. history first). Participants were then asked to allocate blame for the conflict to one group over the other. Following this judgment of blame, participants recorded their thoughts and feelings regarding this judgment into an audio recorder. These recordings were then played back while they used the Mouse Paradigm to express the feelings portrayed in their recordings. Results indicated no relationship between explicit prejudice and allocation of blame. Implicit prejudice scores were strongly related to allocation of blame, with increases in IAT scores positively correlating with blame of the Muslim group. Results also suggested a link between performance on the lA T and the Mouse Paradigm. More specifically, the results suggest that IAT performance may predict performance on the Mouse Paradigm. Additional results provided by the Mouse Paradigm provided insight into the deliberative processes taking place during the allocation of blame. Future research should explore the link between lA T scores and Mouse Paradigm performance and should be extended to include other forms of the lAT.

Show moreEighteen rats were used to study two procedures for the extinction of discriminated avoidance. One group (OE) was placed on extinction defined by presenting shocks as programmed but independently of the S's responses, while the other group (CE) was placed on classical extinction defined by the removal of all shocks. The two procedures were compared in terms of rate of decline and terminal level of extinction performance. In addition, the two groups were placed on a discrimination reversal task in order to assess each procedure's effects on a new learning problem. The CE group reached a lower level of extinction performance in a fewer number of blocks than the OE Ss. Furthermore, the CE Ss were inferior to the OE Ss in terms of discrimination reversal performance as well. An interpretation of the results in terms of the removal and reinstatement of cues was offered although an alternative explanation relating to a change in the motivational states of the two groups during extinction was also presented. The interpretation in terms of the presence or absence of cues seemed to account for more of the present findings than the traditional one advocating changes in motivational levels resulting from the two divergent extinction operations.

Show moreCognitive theorists hypothesize two types of cognitive processes (e.g., automatic and effortful) which may influence human information processing. This thesis investigates age differences in when children use intralist associative relationships (thought to be automatic in nature) to identify other (categorical) relations. Use of conceptual/ categorical relations to organize recall is thought to be effortful in nature. Sixty children each from grades 3, 5, 7, and 9 were presented orally with lists of 20 words under free-recall instructions. Results provide support for the position that recall memory of young children is mediated primarily by associative rather than conceptual relationships. Also, partial support was obtained for the three stage model of the development of organization proposed by Bjorklund and Zeman (1982). However, the model's prediction of when children will optimally use associative relationships to identify categorized relations was inaccurate. These results indicate that older childrens' recall can be facilitated by automatic cognitive processes resulting in higher levels of clustering (organization) and recall.

Three trials used the same word list on each trial, while three trials used different word lists on each trial. Half of the participants received the different word list trials first while the order was reversed for the remaining participants. Results were analyzed for differences between recall groups, type of word list used, and presentation order of the trials. High recallers demonstrated stronger temporal patterns of study behaviors than did low recallers (as measured by Fourier analysis of time series data). High recallers also showed stronger tendencies to use behaviors that facilitated performance in close temporal proximity. Type of word list affected recall and temporal patterns of a portion of the study behaviors analyzed.

Show moreIn this thesis the transition region between two modes of behavior is explored using a novel technique, delayed feedback, and a variety of dynamical systems measures. In a previous study, Engstrom, Kelso, and Holroyd (to appear) established the existence of a transition between anticipatory and reactive behavior in a sensorimotor coordination task as a control parameter (frequency) was varied. Here, in order to explore the hypothesis that the behavioral dynamics during this transition are intermittent in character, subjects were asked to synchronize with a metronome that was actually a delayed copy of their own response pattern. The use of delayed feedback was expected to destabilize the behavioral dynamics enough to allow the observation of hypothesized intermittent phenomena. Use of delayed feedback was shown to destabilize synchronization, resulting in the emergence of a new behavioral pattern in the transition region that exhibited complex "bursting" dynamics. Analysis revealed that this bursting behavior displays many of the characteristics common to intermittency, which supports the idea that the anticipation-reaction transition is the result of a neurobehavioral dynamical system losing stability. Living in the vicinity of instabilities may be an important mechanism for biological organisms to maintain both flexibility and stability.

From a sociocultural learning perspective, we examined five year old children's arithmetic strategy use, in a game context, with the most likely of mentors for a young child, his or her parents. Children played three games of a modified version of "Chutes and Ladders" with one of their parents. Children's strategy use and parents' behavior were coded and analyzed. Results indicate that parents usually provided appropriate support to their children, providing more direction and assistance to the children who required them, and less to those who did not.

Eighty-two women and 32 men (mean age 71 years) used the Rochester Interaction Record to record quantitative and qualitative information about every interaction which lasted more than 10 minutes for 2 weeks. Gender analyses revealed that same-gender interaction was most common for all participants (spouse excluded). Males and females reported that interactions with females only were more intimate than interactions with males only or with mixed-gender others. Spousal analyses showed that participants interacted with spouse as much as with same-gender others, however, spousal interactions were reported to be more intimate than same or opposite-gender interactions. Participants reported interacting with nonfamily more than with family. In addition, interactions with family were reported to be qualitatively equal to interactions with nonfamily. For future research it will be important to consider how these quantitative and qualitative characteristics of interaction relate to well-being.

This study presents a novel approach to stereotype assessment by focusing on children's idiosyncratic stereotypes (as opposed to number of commonly shared stereotypes, which do not provide detailed information about the types of stereotypes individual children hold). Participants were 305 children in grades three through eight (Mage = 10.8 years). Independent variables included children's stereotypes of 62 contextually tagged behaviors and gender identity (comprising five dimensions). Interactive influences of children's stereotypes and gender identity on self-efficacy were investigated. As expected, stereotypes and gender identity worked together to predict children's self-efficacy perception for the 62 behaviors. These findings suggest that the role of gender identity is important in the adoption of personally held gender stereotypes.

Show moreJealousy results from the fear of loss of an important relationship partner or his/her exclusive attention (Neu, 1980; Tov-Ruach, 1980). Infants are dependant on their caregivers for basic needs and emotional support. Therefore, if an infant perceives that a rival threatens the parent-child dyad relationship, it is possible that the infant will respond in a jealous manner just as adults do when their important relationships are threatened . Although infants have limited emotional understanding, Palmer and Palmer (2002) suggest that jealousy evolved out of other resource-protecting drives. Because parental care is a valuable resource, supporting survival, infants may have at least precursory jealousy capabilities. Research on infant jealousy is minimal however, Hart and Carrington (2002) characterized approach responses to the loss of maternal attention to a life-like doll as jealousy. The purpose ofthe current repeated-measures research design is to provide a conceptual replication of previous infant jealousy research. Whether infant jealousy responses are moderated by individuals approach or withdrawal tendencies, is still to be determined and is another focus of the current research. Temperamental characteristics may influence emotional responses and asymmetrical frontal brain activity is associated with individual differences in emotional responding (see Coan & Allen, 2004 for a review). Therefore baseline electroencephalography (EEG) is collected in the current research followed by subjecting 15 infants (mean age = 12.87 months) to two maternal ignoring conditions, one involving the mother attending to a social object (lifelike doll) and a control condition in which the mother attends to a non-social object (book). Results show that infants respond differentially to the two conditions with increased approach behaviors, arousal, and negative affect in the doll condition. The infants' responses in the social-object condition are identified as jealousy, suggesting that infants are capable of at least some complex emotional experiences. v

A key prediction of dynamic social impact theory is that such phenomena as clustering and polarization of attitudes will emerge from social interactions among spatially distributed people. Study One, using a group of 24 people corresponding with their neighbors about an attitudinal topic, found both substantial polarization and a suggestive tendency toward clustering. Studies Two and Three, using 192 people organized into 48 24-person groups, provide strong empirical support for the emergence of clustering and incomplete polarization, and extend the findings to two alternative spatial structures. As predicted, a control geometry, involving random connections without any spatial organization, failed to produce clustering. Directions for future research are discussed.

The present study explored the psychophysiological effects of mindfulness meditation over a 10 week-period on a sample of 2nd-and 4th-grade children. Electroencephalograph (EEG) asymmetry and coherence were recorded at baseline and immediately after the meditation intervention for the experimental group, and at baseline and after 10 weeks for the control group. Measures of affect, behavioral motivation, creativity, and depression were also administered. The primary findings indicated that when improvement in depressive symptoms occurred for 4th-grade students who were somewhat engaged in meditation practice, left-sided frontal EEG activity was also more prominent. Additionally, 4th-grade students who actively participated in meditation practice experienced decreases in self-reported levels of negative affect. Results suggest that mindfulness meditation is beneficial for improving 4th-grade students’ mood and brain regions associated with mood.

Twenty-four male albino rats, one hundred and tweny days old, were divided into four groups and differentially preadapted in Skinner-boxes to 236.90, 77.25, 22.87, and 1.27 apparent foot-candles for 10 minutes, without access to a bar. Immediately following this period the Ss were allowed to respond under continuous reinforcement to a postadaptation stimulus of 236.90 apparent foot-candles. Measurement in terms of bar pressing indicated that the four groups extinguished differentially over six days. The control group, for whom the discrepancy bwtween preadaptation magnitude and postadaptation stimulus remained zero, was found most resistant to extiction during this period. Additionally, increases in the discrepancy between the pre- and postadaptation magnitudes led to experimental groups. The implications of these data for the proposition of stimulus definitions in terms of behaviorally effective magnitudes were discussed.

Show moreThe observation of contrast effects (CE) in response to differential relnforcenent has subsequently elicited a diversity of experimental results and theoretical interpretations. Adaptation Level (AL ) concepts have provided a mechanism for integrating such data within a psychophysical frame-of-reference approach. The application of this approach to the somewhat neglected area of response-produced stimuli associated with effort, suggests that proprioceptive stimuli may be effectively evaluated in a simllar manner. Following shifts in the amount of effort required to produce a constant reward magnitude, performance measures demonstrated positive and negative contrast effects (PCE; NCE) in relation to an appropriate control performance. Data analysis suggested that the combined effects of greater effort and shift conditions tended to increase resistance to extinction. The findings are not consistent Kith traditional (e. g., Hull, Spence) concepts with regard to CE and the influence of effort on performance. It is suggested that such effects are more consistent with a contextual, or frame-of- reference, viewpoint.

- Abstract/Description

Anstis, et al. (1985) have reported that under certain conditions the visual system adapts and the perception of apparent motion breaks down. The present research indicates that breakdown is actually a result of same-place mechanisms successfully competing with motion-detecting mechanisms. Thus, the perception of stationarity (with flicker) can occur at the start of a trial and spontaneously switch to the perception of motion, or vice versa. The response of same-place mechanisms depends on...
Show moreAnstis, et al. (1985) have reported that under certain conditions the visual system adapts and the perception of apparent motion breaks down. The present research indicates that breakdown is actually a result of same-place mechanisms successfully competing with motion-detecting mechanisms. Thus, the perception of stationarity (with flicker) can occur at the start of a trial and spontaneously switch to the perception of motion, or vice versa. The response of same-place mechanisms depends on the zero-hertz energy at each location of an apparent motion stimulus, whereas the response of motion mechanisms depends on the time-varying energy. Average luminance, luminance contrast, the temporal symmetry of the apparent motion display, and relative phase are manipulated to investigate competition between same-place and motion-detecting mechanisms.

The role of affect in children's (Grades 3-8) achievement motivation was assessed using peer-, teacher-, and self-report measures of perceived academic ability, affect, and conduct. Relationships between the measures and three types of achievement test scores were studied by correlational analyses as were associations with grade point average in the 6th-8th grade sample. The hypothesis that peer- and teacher reports of children's ability, affect, and conformity are related to children's...
Show moreThe role of affect in children's (Grades 3-8) achievement motivation was assessed using peer-, teacher-, and self-report measures of perceived academic ability, affect, and conduct. Relationships between the measures and three types of achievement test scores were studied by correlational analyses as were associations with grade point average in the 6th-8th grade sample. The hypothesis that peer- and teacher reports of children's ability, affect, and conformity are related to children's achievement was supported and indicated that others' perceptions may be more significant than self-reports in this respect. The independent contribution of children's affect to achievement motivation was demonstrated for older children for the grade point measure. Pervasive gender differences were observed, and implications for future research on self-presentation factors were discussed.

Few experiments have examined the effects of attribute processing on purchase intentions. This experiment predicts a function of the left prefrontal cortex (PFC) is to process brand-name products for their attributes. Hemodynamic response was measured in bilateral PFC from 48 participants during a study task, where participants processed brand-name products using various attribute processing types (once using one attribute, twice using the same attribute, and twice using two different...
Show moreFew experiments have examined the effects of attribute processing on purchase intentions. This experiment predicts a function of the left prefrontal cortex (PFC) is to process brand-name products for their attributes. Hemodynamic response was measured in bilateral PFC from 48 participants during a study task, where participants processed brand-name products using various attribute processing types (once using one attribute, twice using the same attribute, and twice using two different attributes), and during a purchase intention test, where participants chose to purchase novel or previously processed brand-name products. Analysis of variance compared differences in hemodynamic response as a function of cortical structure, Type of Processing, and task. Results demonstrated repetition suppression in the left PFC for brand-name products that were previously processed for multiple attributes. Findings suggest processing different attributes of the same brand-name product bias purchase intentions, where participants were more likely to purchase brand-name products processed for multiple attributes.
