Do materialism,intrinsic aspirations,and meaning in life predict students’ meanings of education?

Though there is a deep literature on factors that predict college attendance and on the effects of college attendance on students’ development, there has been little research on what education actually means to students themselves. This study was conducted to examine whether materialism, intrinsic aspirations, and the search for meaning in life predicted a set of ten meanings that students are known to associate with their education. Multiple regression analyses indicated that students who were high on materialism viewed their education as an opportunity to gain independence, a chance to establish relationships, and a source of stress. Individuals high on intrinsic aspirations were more likely to see education as a time for career preparation, gaining independence, exploring future life directions, learning, engaging in personal growth, establishing social relationships, and learning skills to make a difference in the world, but they were less likely to view education as an escape from future responsibilities. As expected, the findings also revealed that individuals who sought meaning in life viewed education as a way to gain independence, explore life directions, engage in personal growth, establish relationships, learn skills that will help change the world, and escape future responsibilities.     

Friend or foe? The role of latent inhibition in predator and non-predator labelling by coral reef fishes

In communities of high biodiversity, the ability to distinguish predators from non-predators is crucial for prey success. Learning often plays a vital role in the ability to distinguish species that are threatening from those that are not. Many prey animals learn to recognise predators based on a single conditioning event whereby they are exposed to the unknown predator at the same time as alarm cues released from injured conspecifics. The remarkable efficiency of such learning means that recognition mistakes may occur if prey inadvertently learn that a species is a predator when it is not. Latent inhibition is a means by which prey that are pre-exposed to an unknown species in the absence of negative reinforcement can learn that the unknown animal is likely not a threat. Learning through latent inhibition should be conservative because mistakenly identifying predators as non-predators can have fatal consequences. In this study, we demonstrated that a common coral reef fish, lemon damselfish, Pomacentrus moluccensis can learn to recognise a predator as non-threatening through latent inhibition. Furthermore, we showed that we could override the latent inhibition effect by conditioning the prey to recognise the predator numerous times. Our results highlight the ability of prey fish to continually update the information regarding the threat posed by other fishes in their vicinity.     

More men run relatively fast in U.S. road races, 1981-2006: a stable sex difference in non-elite runners

Recent studies indicate that more men than women run fast relative to sex- specific world records and that this sex difference has been historically stable in elite U.S. runners. These findings have been hypothesized to reflect an evolved male predisposition for enduring competitiveness in "show-off" domains. The current study tests this hypothesis in non-elite runners by analyzing 342 road races that occurred from 1981-2006, most in or near Buffalo, NY. Both absolutely and as a percentage of same-sex finishers, more men ran relatively fast in most races. During the 1980s, as female participation surged, the difference in the absolute number of relatively fast men and women decreased. However, this difference was stable for races that occurred after 1993. Since then, in any given race, about three to four times as many men as women ran relatively fast. The stable sex difference in relative performance shown here for non-elites constitutes new support for the hypothesis of an evolved male predisposition for enduring competitiveness.     

Discriminating between the effects of valence and salience in the Implicit Association Test

The Implicit Association Test (IAT) is the most widely used indirect measure of attitudes in social psychology. It has been suggested that artefacts such as salience asymmetries and familiarity can influence performance on the IAT. Chang and Mitchell (2009) proposed that the ease with which IAT stimuli are classified (classification fluency) is the common mechanism underlying both of these factors. In the current study, we investigated the effect of classification fluency on the IAT and trialled a measure-the split IAT-for dissociating between the effects of valence and salience in the IAT. Across six experiments, we examined the relationship between target classification fluency and salience asymmetries in the IAT. In the standard IAT, the more fluently classified target category was, all else being equal, compatible with pleasant attributes over unpleasant attributes. Furthermore, the more fluently classified target category was more easily classified with the more salient attribute category in the split IAT, independent of evaluative associations. This suggests that the more fluently classified category is also the more salient target category.     

Nonrational processes in ethical decision making

Most current ethical decision-making models provide a logical and reasoned process for making ethical judgments, but these models are empirically unproven and rely upon assumptions of rational, conscious, and quasilegal reasoning. Such models predominate despite the fact that many nonrational factors influence ethical thought and behavior, including context, perceptions, relationships, emotions, and heuristics. For example, a large body of behavioral research has demonstrated the importance of automatic intuitive and affective processes in decision making and judgment. These processes profoundly affect human behavior and lead to systematic biases and departures from normative theories of rationality. Their influence represents an important but largely unrecognized component of ethical decision making. We selectively review this work; provide various illustrations; and make recommendations for scientists, trainers, and practitioners to aid them in integrating the understanding of nonrational processes with ethical decision making.     

A feasibility study of Acceptance and Commitment Therapy for emotional dysfunction following psychosis

The experience of psychosis can lead to depression, anxiety and fear. Acceptance and Commitment Therapy (ACT) facilitates individuals to accept difficult mental experiences and behave in ways that are consistent with personally held values. This study was a single (rater) blind pilot randomised controlled trial of ACT for emotional dysfunction following psychosis. Twenty-seven participants with psychosis were randomised to either: ten sessions of ACT plus treatment as usual (TAU) or TAU alone. The Hospital Anxiety and Depression Scale, Positive and Negative Syndrome Scale, Acceptance and Action Questionnaire, Kentucky Inventory of Mindfulness Skills and Working Alliance Inventory were used. Individuals were assessed at baseline and 3 months post-baseline. The individuals randomised to receive ACT found the intervention acceptable. A significantly greater proportion of the ACT group changed from being depressed at time of entry into the study to not being depressed at follow-up. The ACT group showed a significantly greater increase in mindfulness skills and reduction in negative symptoms. Results indicated that individuals randomised to ACT had significantly fewer crisis contacts over the study. Changes in mindfulness skills correlated positively with changes in depression. ACT appears to offer promise in reducing negative symptoms, depression and crisis contacts in psychosis.     

Selective attention in human associative learning and recognition memory

Four experiments examined the role of selective attention in a new causal judgment task that allowed measurement of both causal strength and cue recognition. In Experiments 1 and 2, blocking was observed; pretraining with 1 cue (A) resulted in reduced learning about a 2nd cue (B) when those 2 cues were trained in compound (AB+). Participants also demonstrated decreased recognition performance for the causally redundant Cue B, suggesting that less attention had been paid to it in training. This is consistent with the idea that attention is preferentially allocated toward the more predictive Cue A, and away from the less predictive Cue B (e.g., N. J. Mackintosh, 1975). Contrary to this hypothesis, in Experiments 3 and 4, participants demonstrated poorer recognition for the most predictive cues, relative to control cues. A new model, which is based on N. J. Mackintosh's (1975) model, is proposed to account for the observed relationship between the extent to which each cue is attended to, learned about, and later recognized     

Intent Attributions and Aggression: A Study of Children and their Parents

This research aimed to further clarify the relationship between children's self-reported hostile intent attributions (for ambiguous instrumental or relational provocations) and peer-reported aggression (physical and relational) in 500 fourth-grade children. In addition, we examined whether parents' intent attributions might predict children's intent attributions and aggression. Both parents (mothers and fathers) in 393 families completed intent attribution questionnaires. Results showed, consistent with past research, that boys' instrumental intent attributions were related to physical aggression. Children's relational intent attributions, however, were not associated with relational aggression. Contrary to expectations, most children responded with hostile intent attributions for relational provocations. Finally, in regard to parent-child connections, maternal intent attributions correlated with children's intent attributions whereas paternal intent attributions corresponded with children's relational aggression.     

Extinction in human learning and memory

In two experiments, participants were given extinction training in a human causal learning task. In both experiments, three critical experimental cues were paired with different outcomes in a first phase of training and were then extinguished in a second phase. Three control cues were given the same treatment in the first phase of training, but were not then presented in the second phase. Participants' ability to correctly identify the outcome with which each cue had been paired in the first phase was lower for extinguished than for control cues. Causal attributions to the extinguished cues were also lower than those to the control cues, a difference that correlated with outcome memory. These data are consistent with the idea that extinction in causal judgement is due, at least in part, to a failure to remember the cue-outcome relationship encoded in the first phase of training.
