Overgeneral memory extends to pictorial retrieval cues and correlates with cognitive features in posttraumatic stress disorder

Individuals with posttraumatic stress disorder (PTSD) show overgeneral memory (OGM) when retrieving autobiographical memories to word cues. We investigated whether OGM extends to picture cues and whether it is related to PTSD symptoms and cognitions. Trauma survivors with (n = 29) and without (n = 26) PTSD completed the standard Autobiographical Memory Test (AMT) and a novel picture version. Compared to the no-PTSD group, the PTSD group showed OGM in both test versions. Pictures facilitated specific memory retrieval, but this effect was no longer significant when verbal intelligence or depressive symptoms were controlled. OGM correlated with PTSD symptoms and perceived self-change; with intrusive memories, their perceived "nowness," responses to intrusions (thought suppression, rumination, dissociation), and negative interpretations of symptoms.     

Will Julia Roberts harm Nicole Kidman? Semantic priming effects during face naming

Three experiments are reported, which examine whether face naming is vulnerable to semantic competition in a similar way to object naming. Previous experiments with object naming have shown that a related prime picture presented 3 trials before a target picture results in an increase in error rate and naming latencies when compared to unrelated prime conditions. The experiments here use the same paradigm, with errors as the main dependent variable. In Experiment 1, the prime and target faces were from the same occupational category (e.g., politicians, actors), and in Experiment 2, the primes and target faces were also associated to each other. In Experiment 3, the prime was presented as a name to be read aloud. Unrelated filler stimuli intervened between prime and target. In all experiments, there was a reduction in target-naming errors in the related conditions, and in Experiment 3 this was shown to be largely a reduction in naming failures. The results suggest that related name representations for famous people are not activated in parallel and in competition, and that there is some evidence for a relatively long lasting facilitatory effect. These results require some modification to any serial account of face naming to differentiate it from the generally well-established serial account of object naming.     

Renewal of cue-elicited urge to smoke: implications for cue exposure treatment

The effects of cue exposure therapy are limited, because renewal after extinction is an important source of relapse. In this study, 33 smokers were exposed to a cue predicting smoking availability and a cue predicting smoking unavailability in one context (acquisition context A). Following extinction in another context (extinction context B), a test for renewal took place in the original acquisition context A (i.e. ABA renewal). Urge to smoke was measured using a Visual Analogue Scale. Renewal of differential conditioned urge responding occurred when participants were tested in the acquisition context, while differential urge responding remained extinguished when tested in the extinction context. This experiment provides evidence that ABA renewal occurred in smokers. Clinical implications are discussed.     

Using dynamic field theory to rethink infant habituation

Much of what psychologists know about infant perception and cognition is based on habituation, but the process itself is still poorly understood. Here the authors offer a dynamic field model of infant visual habituation, which simulates the known features of habituation, including familiarity and novelty effects, stimulus intensity effects, and age and individual differences. The model is based on a general class of dynamic (time-based) models that integrate environmental input in varying metric dimensions to reach a single decision. Here the authors provide simulated visual input of varying strengths, distances, and durations to 2 coupled and interacting fields. The 1st represents the activation that drives "looking," and the 2nd, the inhibition that leads to "looking away," or habituation. By varying the parameters of the field, the authors simulate the time course of habituation trials and show how these dynamics can lead to different depths of habituation, which then determine how the system dishabituates. The authors use the model to simulate a set of influential experiments by R. Baillargeon (1986, 1987a, 1987b) using the well-known "drawbridge" paradigm. The dynamic field model provides a coherent explanation without invoking infant object knowledge. The authors show that small changes in model parameters can lead to qualitatively different outcomes. Because in typical infant cognition experiments, critical parameters are unknown, effects attributed to conceptual knowledge may be explained by the dynamics of habituation.     

Some Variables in the Blue (Red) Phenomenon

The relation between spontaneous color choices and ratings of the prototypicality, conspicuousness, and pleasantness of colors was studied in a sample of Dutch college students. Pleasantness, not prototypicality or conspicuousness, determined the four most frequent spontaneous choices—red, blue, green, and purple. Subjects considered blue the most pleasant of the 12 colors studied, which suggests a pleasantness explanation for the “blue phenomenon” found in some countries. The predominance of red as a spontaneous choice replicated the results of previous studies in the Netherlands. Red also was rated highest in prototypicality but was not rated higher by red choosers than by choosers of other colors, so that a simple prototypicality explanation was rejected. Further analysis showed that the predominance of red as the spontaneous choice of Dutch subjects can be explained by an interaction between prototypicality and pleasantness: Subjects tended to choose red when they rated it highly on both variables.     

A Dialectic on Validity: Where We Have Been and Where We Are Going

It has been suggested that the primary issue in considerations of validity today is the discrepancy between currently accepted theory and the practice of validation. The reason for this discrepancy may be that although considerable discussion has taken place in educational measurement and psychometrics regarding changes in our conceptions of validity, that has not been the case more generally in the social and behavioral sciences. A dialectic on the current status of validity theory for social and behavioral scientists is presented to help bridge this gap.     

A Glimpse into Co-Occupations: Parent/Caregiver's Support of Young Children's Playfulness Scale

Cooperative play between parents/caregivers and children is a positive and significant contributor to the development of children’s emotional, social, and cognitive skills and may set the stage for the formation of co-occupations. This article discusses the rationale for the development of Parent/Caregiver’s Support of Young Children’s Playfulness (PSYCP), an assessment that is based on children’s play and playfulness, adult’s playfulness, and parent–child interaction. The use of the PSYCP to assess co-occupations will allow therapists to identify the specific behaviors that either hinder or support playfulness and mutual play.
