Judgments of remembering: the revelation effect in children and adults

When items on a recognition test are presented as a series of increasingly complete fragments rather than being presented initially in their fully intact form, adults' judgments of recognition exhibit an increased tendency to judge items as "old," an illusion of recognition referred to as the revelation effect. The present study used pictorial stimuli to test for a revelation effect with 4-year-olds, 8-year-olds, and adults (N = 76). A reliable revelation effect was found at all ages tested, indicating that the complex fluency-of-processing discrepancy detection and attribution mechanisms thought to be responsible for the effect function similarly across an age range from 4-years-of-age through adulthood. It was also found that the recognition decisions of the 8-year-olds and the adults were affected by how quickly they were able to identify a picture during the revelation phase of the recognition test. This effect was not found with the 4-year-olds, suggesting an age difference in the awareness and strategic use of an implicit memory effect when making explicit judgments of recognition.     

Facing Up to Hopelessness: A Dialogal Phenomenological Study

Hopelessness is a fundamental human experience, and yet is often considered evidence either of sin or of illness. This dialogal phenomenological study, based on in-depth interviews, takes a fresh look at despair as experienced by people across a variety of ages and contexts, and at the consequences and outcomes of these feelings. At the heart of despair is a sense of isolation, impotence, and an immutable future, and yet it may give rise to new purpose or a new understanding and acceptance of life with its possibilities and limitations. The therapeutic implications of this understanding of despair are discussed with a focus on how presence can be healing.     

Attentional resource and processing speed limitations during sentence processing in Parkinson's disease

Several studies have suggested that patients with Parkinson's disease (PD) have sentence comprehension difficulty in part because of their limited executive resources. However, these assessments confound the executive resources contributing to sentence comprehension with the resources needed for task performance. In the present study, we used a word detection technique that minimizes task demands in order to evaluate attentional and processing speed resources during the comprehension of simple sentences without subordinate clauses and sentences containing subject-relative and object-relative center-embedded subordinate clauses. We found that PD patients have poor sensitivity to phonetic errors embedded in unbound grammatical morphemes, regardless of the clausal structure of the sentence, suggesting difficulty attending to grammatical morphemes. We also found that PD patients are significantly slowed in their sensitivity to phonetic errors in content words embedded in object-relative center-embedded sentences. Slowed sensitivity to content words in object-relative sentences was correlated with timed executive measures of planning. On a traditional measure of comprehension, these PD patients were impaired for sentences containing object-relative center-embedded clauses compared to sentences with subject-relative center-embedded clauses, and comprehension of object-relative sentences was correlated with executive measures. Our findings are consistent with the claim that limited executive resources for strategic attention and processing speed contribute to the sentence comprehension difficulties of PD patients.     

Temporal Induction of Missing Birdsong Segments in European Starlings

Four European starlings (Sturnus vulgaris) discriminated a 300-ms segment of starling song from a 300-ms segment of budgerigar song in three contexts in a two-choice key-peck operant discrimination task. In the starling-song context, on each trial, one of the song segments was presented in the context of starling song; in the budgerigar-song context, the segments were presented in the context of budgerigar song. In the no-song context, the song segments were presented outside of a song context. On occasional unreinforced probe trials, the song segments were replaced by either white noise or silence. On noise trials in the two song contexts, but not on silent trials in the song contexts or noise trials in the no-song context, the starlings were significantly more likely to respond to the key associated with the starling song segment than to the key associated with the budgerigar song segment. This effect was especially pronounced in the starling-song context. The results indicate that noise induces perceptual restoration of missing birdsong segments in songbirds.     

Bringing order to the arbitrary: one- to two-year-olds’ recall of event sequences

Recall by children ages 16–32 months was tested on event sequences that were either arbitrarily ordered or were constrained by enabling relations. Even the youngest children reliably recalled the enabling sequences. It was not until 20 months and older that the children performed at above-chance levels on the arbitrarily ordered events.     

Situational and Individual Influences on Judgments of Hostile Environment Sexual Harassment1

The current research examines the judgment processes of third-party evaluators of sexual harassment situations. Four situational variables were hypothesized to influence ratings of situation appropriateness and judgments of sexual harassment. The evaluator's gender and personality also were hypothesized to influence both ratings. Participants were 73 male and 51 female undergraduate students. Results indicated that behavior severity and victim response significantly influenced ratings. The frequency of the behavior influenced appropriateness ratings, but interacted with behavior severity for harassment judgments. The effects of the gender of the evaluator were mediated by the evaluator's level of tolerance for harassment. The effects of the power relationship and rater personality were not significant.     

Empathy, Expectations, and Situational Preferences: Personality Influences on the Decision to Participate in Volunteer Helping Behaviors

Although considerable evidence indicates that dispositional empathy is associated with the degree of help that observers will offer needy targets, little is known about the effect of empathy on one's initial willingness to enter situations in which such needy targets might be found. Three studies were conducted to evaluate two related propositions: (1) that dispositional empathy influences such situational preferences, and (2) that this influence is mediated by the expectancies one holds regarding the emotions likely to occur in those situations. Using hypothetical judgments, Study 1 found support for both propositions. Study 2, in which participants believed that their responses actually committed them to encountering needy targets, provided further support for the model, as did Study 3, which examined the experiences of actual community volunteers. The theoretical and practical implications of these findings are discussed.     

TRAINING AND GENERALIZATION OF SEXUAL ABUSE PREVENTION SKILLS FOR WOMEN WITH MENTAL RETARDATION

Previous research has shown that behavioral skills training to teach sexual abuse prevention skills to women with mental retardation results in skill acquisition but poor generalization. In this investigation we evaluated procedures for enhancing generalization following training. Five women with mental retardation received 10 behavioral skills training sessions followed by in situ training when the skills did not fully generalize. Behavioral skills training resulted in skill acquisition and in situ training produced generalized responding during naturalistic assessments.
