Reduction of disrupted caregiver behavior using modified interaction guidance

The present study is a reanalysis of a preexisting study examining the usefulness of the Atypical Maternal Behavior Instrument for Assessment and Classification (AMBIANCE; Bronfman, Parsons, & Lyons‐Ruth, 1999) measure as an indicator of efficacy in reducing disrupted caregiver behavior in two brief interventions. The current study examines the rate of change in the display of disrupted caregiver behavior over the course of an attachment‐based intervention (Modified Interaction Guidance) in a group of 11 caregiver‐infant dyads referred to a tertiary care clinic for feeding problems. The AMBIANCE was utilized as an indicator of change in disrupted behavior following an assessment feedback session and three intervention sessions. Results showed a significant decrease in the total display of disrupted caregiver behaviors, as well as a change in classification from disrupted to not‐disrupted, after receiving both feedback from the assessment and the first treatment session. A qualitative analysis of the data further revealed different patterns of change between caregivers. These findings provide preliminary empirical support suggesting that a reduction of disrupted caregiver behavior can be observed relatively quickly after the commencement of the Modified Interaction Guidance intervention.     

Stimulus exposure time and perceptual memory

The recent explosion of research on implicit memory has facilitated the examination of perceptual and conceptual processes in the encoding of information. Nevertheless, stimulus exposure time—the amount of time that a stimulus is physically available to a perceiver’s scrutiny—has received little attention. In the present paper, we examine the effect of stimulus exposure time on three implicit memory measures (word-fragment completion, perceptual identification, and general knowledge) and two explicit memory measures (graphemic cued recall and semantic cued recall). In Experiment 1, we demonstrated that increases in exposure time lead to increases in implicit perceptual memory, but not to implicit conceptual memory, when the encoding task focuses on perceptual features of the stimulus. We replicated this effect in Experiment 2 and demonstrated that increases in exposure time lead to increases in perceptualand conceptual memory when the measures are explicit. Thus, the current experiments demonstrate that manipulations of exposure time lead to dissociations in implicit, but not explicit, memory.     

PERSONALITY AND PERCEPTUAL EXPERTISE:

Abstract— We hypothesized that people become expert at perceiving information that is related to concepts they think about a great deal, because of their extensive perceptual experience with this material To test this idea, we manipulated the capitalization of a series of briefly exposed words If expertise emerges because of perceptual experience, then people should show facilitation identifying words that they think about a great deal, but only when capitalization of these words is consistent with prior perceptual experience with these words Support for this hypothesis was found in two experiments–one in which trait words were presented to depressed and nondepressed subjects, and one in which food words were presented to anorexic and nonanorexic subjects Thus, these experiments demonstrated that personality, as well as personality disorder, has the potential to change the nature of the input people receive from the perceptual system     

Desirable and undesirable masculine and feminine traits in relation to students' dieting tendencies and body image dissatisfaction

Previous research showing greater femininity among overweight persons used measures of masculinity and femininity which have been criticized for conceptual and psychometric reasons. The present study used the Spence-Helmreich measures to examine the interrelationships among socially desirable and socially undesirable instrumental (masculine) and expressive (feminine) traits, body weight, and other attributes of cognitive concern about dieting and weight-related appearance. While body weight was unrelated to these measures of psychological masculinity and femininity, sex differences were found in the relationship of masculinity and femininity to dieting tendencies. dissatisfaction with physical appearance, and achievement motivation in these samples of college undergraduates.
