Photographs as retrieval cues for children

The aim of this study was to evaluate photographs as an alternative type of retrieval aid suitable for pre-school children. Fifty-seven children (age 3;7–6;8 years) participated in a fishing game. Ten days later the children were questioned about the situation under three conditions: group 1 was interviewed only with a context-reinstatement instruction. Group 2 additionally received photos relevant to the game as well as distractor items. Group 3 received both of these aids and was trained in the use of photos. In the photo groups more correct details were remembered compared to the control group. Accuracy in both photo groups was also enhanced by props. These results show that multiple-choice photos combined with a reinstate context instruction are an effective retrieval aid for young children. © 1998 John Wiley & Sons, Ltd.     

Predictors and moderators of improved social-emotional functioning in mothers with substance use disorders and their young children enrolled in a relationship-based case management program

Mothers with substance use disorders (SUDs) typically have trauma histories and psychosocial difficulties that lead to poor social-emotional functioning and disrupted mother–child relationships. This 12-month study explored associations of family adverse circumstances and services (case management, therapeutic, and community-based) received by 57-mothers with SUDs and their infants (less than 24-months-old) with changes in social-emotional functioning. All mothers were enrolled in a relationship-based case management program (Parent–Child Assistance Program [PCAP]) that emphasized connecting mothers to appropriate community services. A subset of mothers was additionally provided a trauma-focused psychotherapeutic intervention (infant–parent psychotherapy [IPP]). Dyads in both treatment groups improved in overall social-emotional functioning as assessed by the Functional Emotional Assessment Scale (FEAS). A combined-sample regression analysis revealed that improved FEAS scores were significantly predicted by the number of community services received but not by PCAP case management hours (IPP was not included in this analysis). More adverse circumstances were associated with less improvement in social-emotional functioning in the children; but among the mothers trauma level did not predict FEAS scores. We also found a moderating effect of trauma: Dyads with relatively more adversity showed a significantly greater association of community services received with improvement in FEAS scores than did those with relatively less adversity.     

Ad hoc Reviewers for the Journal of Motor Behavior

The study of sign languages provides a promising vehicle for investigating language production because the movements of the articulators in sign are directly observable. Movement of the hands and arms is an essential element not only in the lexical structure of American Sign Language (ASL), but most strikingly, in the grammatical structure of ASL: It is in patterned changes of the movement of signs that many grammatical attributes are represented. The “phonological? (formational) structure of movement in ASL surely reflects in part constraints on the channel through which it is conveyed. We evaluate the relation between one neuromotor constraint on movement–regulation of final position rather than of movement amplitude–and the phonological structure of movement in ASL. We combine three-dimensional measurements of ASL movements with linguistic analyses of the distinctiveness and predictability of the final position (location) versus the amplitude (length). We show that final position, not movement amplitude, is distinctive in the language and that a phonological rule in ASL predicts variation in movement amplitude–a development which may reflect a neuromuscular constraint on the articulatory mechanism through which the language is conveyed.     

Emotions as signals of normative conduct

Social interactions are heavily norm-based and these norms need to be learned. For this, the emotional reactions of other's in response to a norm transgression can serve as signals. We were able to show that when a group responds with anger to a norm transgressing behaviour, participants were better able to correctly infer the norm than when the group responded with sadness or emotional neutrality. We further tested a process-model showing that this inference is based on the participants' understanding of the groups' appraisals of the behaviour. That is, participants who were able to reverse engineer the underlying appraisal of norm-incompatibility from the emotion expressions inferred the norm more readily. Humans as a social species, require efficient means to quickly adapt to new situations and to perform flawlessly in social contexts. Emotion information is one of the instruments that can be used in this quest.     

Measuring consciousness in dreams: The lucidity and consciousness in dreams scale

In this article, we present results from an interdisciplinary research project aimed at assessing consciousness in dreams. For this purpose, we compared lucid dreams with normal non-lucid dreams from REM sleep. Both lucid and non-lucid dreams are an important contrast condition for theories of waking consciousness, giving valuable insights into the structure of conscious experience and its neural correlates during sleep. However, the precise differences between lucid and non-lucid dreams remain poorly understood. The construction of the Lucidity and Consciousness in Dreams scale (LuCiD) was based on theoretical considerations and empirical observations. Exploratory factor analysis of the data from the first survey identified eight factors that were validated in a second survey using confirmatory factor analysis: INSIGHT, CONTROL, THOUGHT, REALISM, MEMORY, DISSOCIATION, NEGATIVE EMOTION, and POSITIVE EMOTION. While all factors are involved in dream consciousness, realism and negative emotion do not differentiate between lucid and non-lucid dreams, suggesting that lucid insight is separable from both bizarreness in dreams and a change in the subjectively experienced realism of the dream.
