Further evidence of a robust point-of-view bias in videotaped confessions

Four experiments were conducted to test possible limits on the previously demonstrated point-of-view bias in videotaped confessions. Study 1 showed that deliberation did not eliminate the bias. Study 2 showed that forewarning did not eliminate the bias. Study 3 showed that directing greater attention to the content of the confession did not eliminate the bias. Study 4 showed that using a lengthier, case-based confession also did not eliminate the bias. Taken together, this research clearly indicates that the legal system needs to be concerned with the potential for bias that exists in videotaped confessions.

Cognitive efficiency modes in old age: performance on sequential and coordinative verbal and visuospatial tasks

In an experiment using a large set of verbal and spatial tasks requiring low or high degrees of executive control, 3 distinct age-related effects were found. The smallest effect (no slowing) was tied to lexical tasks with low executive involvement, the largest deficit (age-related slowing factor of 2.2) was tied to visuospatial tasks with high executive involvement, an intermediate level of deficit (slowing factor of 1.7) was found for visuospatial tasks with low executive load and verbal tasks with high executive load. These age-related dissociations were incompatible with any "common cause" formulation. The mechanism responsible for the dissociation between verbal and visual tasks, and between low and high executive load remains to be determined. The latter may reflect capacity limits.     

Can false memories be corrected by feedback in the DRM paradigm?

Normal processes of comprehension frequently yield false memories as an unwanted by-product. The simple paradigm now known as the Deese/Roediger-McDermott (DRM) paradigm takes advantage of this fact and has been used to reliably produce false memory for laboratory study. Among the findings from past research is the difficulty of preventing false memories in this paradigm. The purpose of the present experiments was to examine the effectiveness of feedback in correcting false memories. Two experiments were conducted, in which participants recalled DRM lists and either received feedback on their performance or did not. A subsequent recall test was administered to assess the effect of feedback. The results showed promising effects of feedback: Feedback enhanced both error correction and the propagation of correct recall. The data replicated other data of studies that have shown substantial error perseveration following feedback. These data also provide new information on the occurrence of errors following feedback. The results are discussed in terms of the activation-monitoring theory of false memory.     

On the automatic association between America and aggression for news watchers

Across three experiments, the nonconscious perception of American cues increase the accessibility of aggressive constructs in memory, aggressive and negative judgments of other people, and aggressive displays of behavior following a mild provocation. These effects emerge only for American participants who regularly follow the American political news media. For American participants who do not follow the news, these effects are absent or tend to be in the opposite direction. Participants' political party orientation (Republican vs. Democratic) does not moderate any of the results. Interpretations and implications of the findings are discussed.     

The effect of a salient odor context on memory retrieval in young infants

Three-month-old infants were trained to move a mobile in the presence of a coconut or cherry odor (context). One or 5 days later, the infants were tested for retrieval in the presence of either the same odor, the alternate odor, or no odor. Infants tested with the training odor displayed retention at both intervals; retention was not seen at either interval in the alternate odor or no odor conditions. These data suggest that the odor combines with the mobile to form a compound-stimulus representation of the learned task whose presence after both short (1 day) and long (5 days) intervals is a necessary retrieval cue.     

Using developmental principles to assist preschoolers in developing numeracy and literacy

In a yoked control design, 4-yr.-olds (N = 39) in a Head Start program played numerous structured games involving either the oddity principle or letter identification and letter sounds. The children's mean age was 53.2 mo.; SD = 4.1 mo. Three were Middle Eastern, 14 were Latino, 7 were East African, and 15 were African American. Children showed better mastery of oddity after playing games directed at this concept, and numeracy scores on the Woodcock-Johnson III were better for children who had played this type of game. Woodcock-Johnson III Letter-Word scores for children who had played the oddity and seriation or letter games were equivalent. These results are consistent with other research indicating that the understanding of oddity relations may be a key transitional thinking which supports quantitative and verbal development at the preschool-kindergarten interface. The standardized test scores indicate that guided play directed at this aspect of cognitive growth or more narrowly directed at early literacy can produce equivalent knowledge of letters.     

Using cue words to investigate the distribution of autobiographical memories in childhood

The cue-word technique is frequently used with adults to examine the distribution of autobiographical memories across the life span. Such studies demonstrate childhood amnesia: a paucity of memories of events from the first 3(1/2) years of life, and a gradually increasing number of memories from age 3 to age 7. The pattern is remarkable in light of findings of autobiographical competence among children in the period of life eventually obscured by this amnesia. In the present study, we modified the cue-word task for use with school-age children. Seven- to 10-year-olds successfully generated and dated memories of past events. Girls provided more complete narratives than boys. Across the sample, the resulting distribution of memories was better fit by an exponential than by a power function, implying that early memories may not consolidate and instead remain vulnerable to interference. Implications for explanations of childhood amnesia are discussed.     

Teacher implementation of precorrection and praise statements in Head Start classrooms as a component of a program-wide system of positive behavior support

Although research has clearly supported the use of school-wide positive behavior support (PBS) in elementary school settings, data-based research has not been conducted to support program-wide PBS in early childhood settings. The purpose of this study was to specifically support teachers’ use of universal features of program-wide PBS and to determine whether increases in the use of positive teacher behaviors, including precorrection and praise, were functionally related to decreases in students’ problem behavior. Using a multiple baseline design, three teachers were introduced to an intervention to increase their use of precorrections and specific behavioral praise statements. A relationship was established between the three teachers’ use of key features of program-wide PBS and the reduction of students’ problem behavior in a small group setting. However, findings should be viewed as tentative and future research should explore the relative influence of each of the intervention components on preschool students’ behavior.     

Effectiveness of a Parent Training Program for Improving Children’s Social Behavior

We tested the efficacy of a social skills training program for the parents of school-aged children experiencing socio-emotional problems. Participating families (N = 42) were randomly assigned to one of three conditions: parent social skills training; parent plus parallel child social skills training; or no-treatment control. The two treatment groups did not differ on any of the outcome measures. Treatment was associated with improvements in parent and child social skills knowledge, parent social problem solving, and child emotional functioning. In follow-up analyses examining mechanisms of change, parental attendance and change in child social skills knowledge predicted response to treatment. Overall, our results highlight the utility of engaging parents as primary participants in the treatment of children’s socio-emotional problems and suggest methods for maximizing the impact of such an intervention.
