Visual category-selectivity for faces, places and objects emerges along different developmental trajectories

The organization of category-selective regions in ventral visual cortex is well characterized in human adults. We investigated a crucial, previously unaddressed, question about how this organization emerges developmentally. We contrasted the developmental trajectories for face-, object-, and place-selective activation in the ventral visual cortex in children, adolescents, and adults. Although children demonstrated adult-like organization in object- and place-related cortex, as a group they failed to show consistent face-selective activation in classical face regions. The lack of a consistent neural signature for faces was attributable to (1) reduced face-selectivity and extent of activation within the regions that will become the FFA, OFA, and STS in adults, and (2) smaller volumes and considerable variability in the locus of face-selective activation in individual children. In contrast, adolescents showed an adult-like pattern of face-selective activation, although it was more right-lateralized. These findings reveal critical age-related differences in the emergence of category-specific functional organization in the visual cortex and support a model of brain development in which specialization emerges from interactions between experience-dependent learning and the maturing brain.     

Implicit learning modulates selective attention at sensory levels of perceptual processing

Electrophysiological evidence suggests that attention can be modulated as early as 100 msec after stimulus presentation. However, it is not clear whether these changes are based primarily on stimulus properties such as perceptual load (i.e., the level of perceptual difficulty), or other properties, such as general attentional set or learned expectations concerning perceptual load. Using event-related potentials, this study examined how implicit learning of perceptual load conditions modulates selective attention at sensory levels of perceptual analysis. The results show significant differences in P1 amplitude recorded over occipital areas of the brain as a function of learned expectations of perceptual load, only when perceptual load could be reliably predicted by the preceding stimuli. Moreover, differences in processing were found when both low and high perceptual load conditions could be predicted. These findings suggest that implicit learning modulates the allocation of attention at early stages of perceptual processing.     

Differential effects of age on prospective and retrospective memory tasks in young, young-old, and old-old adults

Remembering to do something in the future (termed prospective memory) is distinguished from remembering information from the past (retrospective memory). Because prospective memory requires strong self-initiation, Craik (1986) predicted that age decrements should be larger in prospective than retrospective memory tasks. The aim of the present study was to assess Craik's prediction by examining the onset of age decline in two retrospective and three prospective memory tasks in the samples of young (18-30 years), young-old (61-70 years), and old-old (71-80 years) participants recruited from the local community. Results showed that although the magnitude of age effects varied across the laboratory prospective memory tasks, they were smaller than age effects in a simple three-item free recall task. Moreover, while reliable age decrements in both retrospective memory tasks of recognition and free recall were already present in the young-old group, in laboratory tasks of prospective memory they were mostly present in the old-old group only. In addition, older participants were more likely to report a retrospective than prospective memory failure as their most recent memory lapse, while the opposite pattern was present in young participants. Taken together, these findings highlight the theoretical importance of distinguishing effects of ageing on prospective and retrospective memory, and support and extend the results of a recent meta-analysis by Henry, MacLeod, Phillips, and Crawford (2004).     

Psychological contracts and their implications for commitment: A feature-based approach

Two studies were conducted to examine the link between employee perceptions of the psychological contract and their affective and normative commitments to the organization. The authors adapt a new approach to the study of psychological contracts by developing a generalizable measure of contract features (e.g., scope; time frame). In Study 1 (N = 301), the authors predicted and found that employees’ perceptions of the contract’s features contributed beyond perceptions of contract type (i.e., transactional; relational) and fulfillment to the prediction of affective and normative commitment. In Study 2 (N = 147), the features measure was refined and results from the first study were largely replicated. In both studies, affective and normative commitment were greater when employees viewed the contract as broad, trust-based, equal, negotiated, tangible, and long-term, and weaker when they saw it as unequal, imposed, and short-term. We also found evidence for patterns of features that correspond to transactional and relational contracts, as well as to recently proposed balanced contracts and I-Deals. Implications for theory and the management of psychological contracts are discussed.     

A Structural Social Psychological View of Gender Differences in Cooperation

We analyze differences in cooperation between men and women in social dilemma settings. Using a structural social psychological framework, we examine how the actor, the encounter, the microstructure, and the macrostructure might influence when gender differences emerge in cooperation. Many of the interaction differences, often linked to innate differences between men and women, are modified when the context is modified. We pay particular attention to how status and identity are connected to such modifications.     

Child versus adult psychoanalysis: Two processes or one?

Child analysis continues to be seen as a different technique from adult analysis because children are still involved in a developmental process and because the primary objects continue to play active roles in their lives. This paper argues that this is a false dichotomy. An extended vignette of the analysis of a latency‐aged girl is used to demonstrate that the psychoanalytic process that develops in child analysis is structurally the same as that in adult analysis. Both revolve around the analysis of resistance and transference and use both to promote knowledge of the patient’s mind at work. And both techniques formulate interventions based on the analyst’s appraisal of the patient’s mental organization. It is hoped that stressing the essential commonality of both techniques will promote the development of an overarching theory of psychoanalytic technique.     

SINGLE‐SAMPLE DISCRIMINATION OF DIFFERENT SCHEDULES' REINFORCED INTERRESPONSE TIMES

Food‐deprived rats in Experiment 1 responded to one of two tandem schedules that were, with equal probability, associated with a sample lever. The tandem schedules' initial links were different random‐interval schedules. Their values were adjusted to approximate equality in time to completing each tandem schedule's response requirements. The tandem schedules differed in their terminal links: One reinforced short interresponse times; the other reinforced long ones. Tandem‐schedule completion presented two comparison levers, one of which was associated with each tandem schedule. Pressing the lever associated with the sample‐lever tandem schedule produced a food pellet. Pressing the other produced a blackout. The difference between terminal‐link reinforced interresponse times varied across 10‐trial blocks within a session. Conditional‐discrimination accuracy increased with the size of the temporal difference between terminal‐link reinforced interresponse times. In Experiment 2, one tandem schedule was replaced by a random ratio, while the comparison schedule was either a tandem schedule that only reinforced long interresponse times or a random‐interval schedule. Again, conditional‐discrimination accuracy increased with the temporal difference between the two schedules' reinforced interresponse times. Most rats mastered the discrimination between random ratio and random interval, showing that the interresponse times reinforced by these schedules can serve to discriminate between these schedules.     

Stepping Stones Triple P: An RCT of a Parenting Program with Parents of a Child Diagnosed with an Autism Spectrum Disorder

Whilst the Triple P Positive Parenting Program has a large evidence base (Sanders, Clinical Child and Family Psychology Review 2:71–90, 1999; Sanders, Journal of Consulting and Clinical Psychology 68:624–640, 2000) and preliminary evidence indicates that Stepping Stones Triple P is also efficacious (Roberts, Journal of Clinical Child and Adolescent Psychology, 35(2):180–193, 2006), to date Stepping Stones has not been evaluated with the ASD population. Fifty-nine families with a child with ASD aged between 2 and 9 participated in this randomized controlled trial. The results demonstrate significant improvements in parental reports of child behaviour and parenting styles with the treatment effects for child behaviour, parental over reactivity and parental verbosity being maintained at follow-up 6 months later. Further, the results suggest significant improvements in parental satisfaction and conflict about parenting as well as a sleeper effect for parental efficacy. The results indicate that Stepping Stones Triple P is a promising intervention for parents of children with ASD. Limitations and future research are also addressed.     

The relationship between pain tolerance and trait aggression: effects of sex and gender role

The literature on pain and aggression has indicated that pain elicits aggression. However, research has generally examined pain as a situational variable and focused less on the dispositional ability of an individual to tolerate pain. The dearth of research on pain tolerance and aggression appears to contradict the existing theory on the aggression‐eliciting effect of pain, in that studies have found a positive relationship between pain tolerance and aggression. The purpose of this study was to determine whether the relationship between pain tolerance and aggression is moderated by sex and whether the positive relationship could be explained by masculine gender role conformity. A sample of 195 collegiate men and women completed trait measures and a laboratory assessment of pain tolerance. Results indicated that correlations between pain tolerance and trait aggression were significant and positive for men but not women. However, when men's conformity to masculine gender role was controlled for, the relationship between pain tolerance and trait aggression was nil and nonsignificant. Results are discussed in reference to socialization and maintenance of masculine status. Aggr. Behav. 35:422–429, 2009. © 2009 Wiley‐Liss, Inc.
