The effects of intervening experiences on children's memory for a physical examination

To examine the extent to which children's long‐term retention is influenced (both positively and negatively) by intervening events, the impact of three programmed experiences on later recall of the details of a physical examination was explored. Four groups of 3‐ and 5‐year‐olds were established, with all children being interviewed immediately after their check‐ups and then again after 12 weeks. The groups, however, differed in terms of their experiences midway through the delay interval. At each age level, children in three experimental groups received either a complete interview about the physical examination, a return visit to the pediatrician's office, or an opportunity to view a videotape that showed a child receiving an actual check‐up. Children in a fourth group served as controls in that they were not seen during the delay period. Recall of standard features was scored, along with responses to questions concerning procedures that did not occur. The results indicated mixed mnemonic effects for the differential intervening experiences. In comparison to the control group, children at each age who had received an additional interview or who had observed the videotape showed elevated open‐ended recall at the 12‐week interview. In addition, the videotape manipulation, as well as the return visit to the doctor's office, was associated with a marked decrease in the 5‐ but not the 3‐year‐olds' accuracy regarding questions about activities not included in the physical examinations. The results are discussed in terms of factors that affect the facilitation and distortion of memory over long temporal delays. Copyright © 2000 John Wiley & Sons, Ltd.     

The impact of perceived experience on likelihood judgments for self and others: an experimental approach

This study examines the effect of an experimental manipulation of perceived experience on self and others' likelihood ratings for a set of relatively commonplace misfortunes. Participants were randomly assigned to a condition in which they were asked whether they had ever experienced the events (designed to induce higher perceived experience) or whether they had done so frequently, typically, etc. (designed to induce lower perceived experience). The manipulation led to increases in ratings of both perceived self‐likelihood and others' likelihood, in ease of imagining the outcome and recall of a past occurrence, and to decreases in perceived control over the events in the higher perceived experience condition. The increases in ease of imagining mediated the impact of manipulated experience on comparative likelihood whereas the decreases in perceived control did not. There was little evidence that event controllability moderated the impact of experience on comparative likelihood for these events. Copyright © 2006 John Wiley & Sons, Ltd.     

Acquiring Explicit Grammatical Knowledge Using the Spanish Verbs <Emphasis Type="Italic">Ser</Emphasis> and <Emphasis Type="Italic">Estar</Emphasis> as Examples

The role of explicit and implicit acquisition of grammatical rules in second language learning was examined by assessing high school students performance after several years of study on the correct use of the Spanish verbs ser and estar. These two verbs are essentially equivalent in use to the English verb “to be,” but there is a complex set of statements that specifies when each is to be used. A 100-item two-choice test in which students from several different high schools receiving instruction in the explicit principles of these two Spanish verbs or receiving immersion training in which no instruction in their grammatical principles was given were examined for the following five factors: (a) general achievement level, (b) comparison of grade level achievement, (c) time allotted to complete the 100-item test, (d) grammatical instruction prior to taking the 100-item test, and (e) comparison of instructional methodology. The results indicated that students receiving explicit instruction in the rules of ser and estar beyond the first year of study achieved slightly higher scores, but that the level of achievement was considered to be poor. Differences between groups for the remaining factors were not significant. It was concluded that successful application of explicitly learned grammatical rules, such as the rules for ser and estar, may not be achievable in the time frame of a two-year high school foreign language course. Considerations regarding implicit and explicit acquisition of grammatical rules in second language learning were presented.

The Attribution of Hostile Intent in Mothers,Fathers and Their Children

Child externalising symptoms are associated with a bias towards attributing hostile intent to others. We examined the role of parental attributions in the development of this hostile attribution bias in children. The parents of 134 children aged 5-7 years responded to hypothetical social scenarios examining a) their general tendency to attribute hostile intent to the ambiguous behaviour of others, and b) hostile attributions made specifically to their child. Children's own attributions of hostile intent and levels of externalising symptomatology were assessed. The results indicated that child externalising symptoms were positively associated with both a generalised tendency towards the attribution of hostile intent and child-specific hostile attributions in parents. Child externalising symptoms were themselves associated with hostile attributions made by the child. However, no direct associations were observed between parental and child attributions of hostile intent. Thus, although the results suggest a role for parental social information processing biases in the development of child externalising symptoms, a direct transmission of such biases from parent to child was not supported.     

Directed forgetting of recently recalled autobiographical memories

In 6 experiments, the authors investigated list-method directed forgetting of recently recalled autobiographical memories. Reliable directed forgetting effects were observed across all experiments. In 4 experiments, the authors examined the impact of memory valence on directed forgetting. The forget instruction impaired recall of negative, positive, and neutral memories equally, although overall, participants recalled fewer unemotional memories than emotional memories. The preexisting organization of memories enhanced the directed forgetting effect, and a release from forgetting occurred only when the forgotten memories were directly cued. The authors discuss the roles of emotion, retrieval dynamics, and organization in these effects and suggest that the directed forgetting of recently recalled autobiographical memories may reflect the inhibition of recently formed memories of remembering, that is, episodic inhibition. The authors consider the implications of these findings for the control of autobiographical remembering in everyday life.     

Social Externalism and First-Person Authority

Social Externalism is the thesis that many of our thoughts are individuated in part by the linguistic and social practices of the thinker’s community. After defending Social Externalism and arguing for its broad application, I turn to the kind of defeasible first-person authority that we have over our own thoughts. Then, I present and refute an argument that uses first-person authority to disprove Social Externalism. Finally, I argue briefly that Social Externalism—far from being incompatible with first-person authority—provides a check on first-personal pronouncements and thus saves first-person authority from being simply a matter of social convention and from collapsing into the subjectivity of “what seems right is right.”

Multimodal Ternus: visual, tactile, and visuo-tactile grouping in apparent motion

Gestalt rules that describe how visual stimuli are grouped also apply to sounds, but it is unknown if the Gestalt rules also apply to tactile or uniquely multimodal stimuli. To investigate these rules, we used lights, touches, and a combination of lights and touches, arranged in a classic Ternus configuration. Three stimuli (A, B, C) were arranged in a row across three fingers. A and B were presented for 50 ms and, after a delay, B and C were presented for 50 ms. Subjects were asked whether they perceived AB moving to BC (group motion) or A moving to C (element motion). For all three types of stimuli, at short delays, A to C dominated, while at longer delays AB to BC dominated. The critical delay, where perception changed from group to element motion, was significantly different for the visual Ternus (3 lights, 162 ms) and the tactile Ternus (3 touches, 195 ms). The critical delay for the multimodal Ternus (3 light-touch pairs, 161 ms) was not different from the visual or tactile Ternus effects. In a second experiment, subjects were exposed to 2.5 min of visual group motion (stimulus onset asynchrony = 300 ms). The exposure caused a shift in the critical delay of the visual Ternus, a trend in the same direction for the multimodal Ternus, but no shift in the tactile Ternus. These results suggest separate but similar grouping rules for visual, tactile, and multimodal stimuli.     

The value of forgetting suicidal thoughts and behavior

This is a prospective longitudinal study examining recollections of suicidal content and correlates of accurate and inaccurate recollection. A primarily at-risk group of young adults (N = 78) who were initially assessed for suicidal ideation and behavior in adolescence, were asked to recall whether they had reported sui- cidal ideation or behavior about six years earlier. In recalling the previous inter- view, the majority of the participants provided consistent reports. However, with regard to those who had previously reported suicidal ideation or behavior, 38% failed to recall prior adolescent suicidal reports. Those who provided accurate reports of prior suicidal content were more symptomatic and were functioning more poorly than those who failed to recall past suicidal content. The implications for clinical assessment practices, research, and theory development are discussed.     

Improving forensic tribunal decisions: the role of the clinician

Three empirical investigations of forensic decision-making were conducted: a study of 104 hearings by a forensic tribunal; an evaluation of which aspects of forensic patients' clinical presentation were empirical predictors of violence; and a survey of forensic clinicians to determine which factors they said they used to assess risk of violent recidivism and which they actually used. Results showed a significant correlation between actuarial risk and clinical advice to the tribunal, and a nonsignificant trend for patients higher in actuarial risk to receive more restrictive dispositions. Psychotic diagnoses and symptoms were not indicators of increased risk of violent recidivism. Clinicians endorsed some empirically valid indicators of risk, but also relied on some invalid indicators. There was also inconsistency between factors clinicians said they used and factors actually related to their hypothetical decision-making. An automated system is presented as an illustration of how the consistency and validity of forensic decisions could be enhanced.
