Item-Cued Directed Forgetting of Related Words and Pictures in Children and Adults: Selective Rehearsal Versus Cognitive Inhibition

The main purpose of this study was to compare the relative importance of selective rehearsal and cognitive inhibition in accounting for developmental changes in the directed-forgetting paradigm developed by R. A. Bjork (1972). In two experiments, children in Grades 2 and 5 and college students were asked to remember some words or pictures and to forget others when items were categorically related. Their memory for both items and the associated remember or forget cues was then tested with recall and recognition. Fifth graders recognized more of the forget-cued words than college students did. The pattern of results suggested that age differences in rehearsal and source monitoring (i.e., remembering whether a word had been cued remember or forget) were better explanatory mechanisms for children's forgetting inefficiencies than retrieval inhibition was. The results are discussed in terms of a multiple process view of inhibition.     

The sociology of adolescent drug and drinking behavior: A review of the state of the field: Part II

This is Part II of our general assessment of the state of sociological research on adolescent substance use. In Part I, presented in the previous issue of this journal, we analyzed the methodological issues in the field and summarized findings on extent and trends of use. Here, we summarize structural, interactional, and attitudinal correlates of teenage drinking and drug behavior. We characterize the field as being theoretically underdeveloped and argue that the place to look for theory to organize empirical generalizations and derive testable hypotheses is among the existing sociological theories of deviance, which have been given scant attention in the adolescent drug and drinking literature. The field of study is in need of primary data collected to test hypotheses from a single general theory that is capable of integrating structural, interactional, and attitudinal variables.     

Creating therapeutic realities via responsibility messages

Abstract

This paper proposes that operating from an ecosystemic epistemology does not preclude a family therapist from focusing on the individual responsibility of each family member. Rather, a systemic therapist can examine the family's pattern of distributing responsibility and map how this perpetuates the presenting problem. Examples from early, middle, and late therapy illustrate how a clinician can design interventions to encourage responsible behavior on the part of each individual, while being mindful of typical transactional patterns in the system     

Importing perceived features into false memories

False memories sometimes contain specific details, such as location or colour, about events that never occurred. Based on the source-monitoring framework, we investigated one process by which false memories acquire details: the reactivation and misattribution of feature information from memories of similar perceived events. In Experiments 1A and 1B, when imagined objects were falsely remembered as seen, participants often reported that the objects had appeared in locations where visually or conceptually similar objects, respectively, had actually appeared. Experiment 2 indicated that colour and shape features of seen objects were misattributed to false memories of imagined objects. Experiment 3 showed that perceived details were misattributed to false memories of objects that had not been explicitly imagined. False memories that imported perceived features, compared to those that presumably did not, were subjectively more like memories for perceived events. Thus, perception may be even more pernicious than imagination in contributing to false memories.     

Measuring Coping in Low-Income European American,African American,and Mexican American Adolescents: An Examination of Measurement Equivalence

We examined the cross-ethnic and cross-language equivalence of the Children's Coping Strategies Checklist (Ayers, T.S., Sandler, I.N., West, S.G. and Roosa, M.W. (1996). A dispositional and situational assessment of children's coping: Testing alternative models of coping. Journal of Personality , 64 (4), 923-958) by assessing item, functional, and scalar equivalence in a sample of 319 European American, African American, and Mexican American adolescents from low-income inner-city families. Depression, as measured by Children's Depression Inventory, was the criterion in the analyses of scalar equivalence. The results suggest considerable cross-ethnic and cross-language measurement equivalence of the Children's Coping Strategies Checklist. The findings also suggest some caution in using the Children's Depression Inventory in comparative studies of African American and Mexican American adolescents or in studies that treat these groups as homogeneous samples.     

Action enhances auditory but not visual temporal sensitivity

People naturally dance to music, and research has shown that rhythmic auditory stimuli facilitate production of precisely timed body movements. If motor mechanisms are closely linked to auditory temporal processing, just as auditory temporal processing facilitates movement production, producing action might reciprocally enhance auditory temporal sensitivity. We tested this novel hypothesis with a standard temporal-bisection paradigm, in which the slope of the temporal-bisection function provides a measure of temporal sensitivity. The bisection slope for auditory time perception was steeper when participants initiated each auditory stimulus sequence via a keypress than when they passively heard each sequence, demonstrating that initiating action enhances auditory temporal sensitivity. This enhancement is specific to the auditory modality, because voluntarily initiating each sequence did not enhance visual temporal sensitivity. A control experiment ruled out the possibility that tactile sensation associated with a keypress increased auditory temporal sensitivity. Taken together, these results demonstrate a unique reciprocal relationship between auditory time perception and motor mechanisms. As auditory perception facilitates precisely timed movements, generating action enhances auditory temporal sensitivity.     

Property rights and the resolution of social conflict

It has long been argued that ownership depends upon social groups' establishing and adhering to rights such as the right to use and to exclude others from using one's own property. The authors consider the application of such rights in the interactions of young peers and siblings, and the extent to which parents support their children in establishing and maintaining the entitlement of owners. They show that children, but not their parents, give priority to ownership in settling property disputes, and argue that diverging models of children's relationships account for these differing perspectives of children and parents.     

Object-based auditory facilitation of visual search for pictures and words with frequent and rare targets

Auditory and visual processes demonstrably enhance each other based on spatial and temporal coincidence. Our recent results on visual search have shown that auditory signals also enhance visual salience of specific objects based on multimodal experience. For example, we tend to see an object (e.g., a cat) and simultaneously hear its characteristic sound (e.g., “meow”), to name an object when we see it, and to vocalize a word when we read it, but we do not tend to see a word (e.g., cat) and simultaneously hear the characteristic sound (e.g., “meow”) of the named object. If auditory–visual enhancements occur based on this pattern of experiential associations, playing a characteristic sound (e.g., “meow”) should facilitate visual search for the corresponding object (e.g., an image of a cat), hearing a name should facilitate visual search for both the corresponding object and corresponding word, but playing a characteristic sound should not facilitate visual search for the name of the corresponding object. Our present and prior results together confirmed these experiential association predictions. We also recently showed that the underlying object-based auditory–visual interactions occur rapidly (within 220 ms) and guide initial saccades towards target objects. If object-based auditory–visual enhancements are automatic and persistent, an interesting application would be to use characteristic sounds to facilitate visual search when targets are rare, such as during baggage screening. Our participants searched for a gun among other objects when a gun was presented on only 10% of the trials. The search time was speeded when a gun sound was played on every trial (primarily on gun-absent trials); importantly, playing gun sounds facilitated both gun-present and gun-absent responses, suggesting that object-based auditory–visual enhancements persistently increase the detectability of guns rather than simply biasing gun-present responses. Thus, object-based auditory–visual interactions that derive from experiential associations rapidly and persistently increase visual salience of corresponding objects.
