The processing of pseudohomophones by adults with a history of developmental language disabilities

Psuedohomophones are nonwords that sound like real words (e.g., BRANE). These items were used to gauge phonological access in adults who have experienced developmental language processing deficits (DLD). The standard effect for these items in lexical decision is an increase in response times over nonpseudohomophone nonwords. This disadvantage reflects phonological processing. In our first experiment the DLD group did not produce this pseudohomophone effect whereas in a second experiment they showed semantic priming effects when pseudohomophones were used as primes in lexical decision. The results therefore indicate that phonological processing of nonwords by adults with DLD can be uncovered under certain carefully controlled experimental conditions.     

Orienting in space and time: Joint contributions to exogenous spatial cuing effects

We examined whether the time course of exogenous spatial-cuing effects is sensitive to the allocation of attention in time. Expectation for a target within a particular time window following the cue was manipulated by varying the proportion of trials that appeared at each of three stimulus onset asynchronies in both a detection task and a two-alternative forced-choice discrimination task. The time course of spatial-cuing effects was sensitive to the temporal expectation manipulation only in the discrimination task. The results are discussed with reference to the role of attentional set in exogenous spatialcuing paradigms.     

Psychopathic traits predict attitudes toward a juvenile capital murderer

The current study manipulated the presence/:absence of psychopathic traits and the ethnicity (Black/:White) of a juvenile capital murderer to examine their impact on layperson attitudes regarding what types of legal sanction were appropriate. Participants (N=360) reviewed a newspaper article concerning a death row inmate who was appealing his sentence primarily based on the fact that he committed the crime when he was 16 years of age. Compared to those in the control condition, those who read a scenario in which the defendant had been described at trial as exhibiting psychopathic traits (e.g. remorselessness, pathological lying) were significantly more likely to support a death sentence and less likely to believe he should receive any treatment in prison. Moreover, participant ratings of the extent to which they believed the defendant exhibited prototypically psychopathic traits (regardless of whether they were in the psychopathy or control condition) also significantly predicted these criterion measures. Ethnic status was relatively less influential, although participants were somewhat more punitive towards a Black defendant than a White defendant when considering the relevance of possible mitigating factors (e.g. history of sexual abuse).     

Sending memorable messages to the old: age differences in preferences and memory for advertisements

Socioemotional selectivity theory holds that people of different ages prioritize different types of goals. As people age and increasingly perceive time as finite, they attach greater importance to goals that are emotionally meaningful. Because the goals that people pursue so centrally influence cognition, the authors hypothesize that persuasive messages, specifically advertisements, would be preferred and better remembered by older adults when they promise to help realize emotionally meaningful goals, whereas younger adults would not show this bias. The authors also predict that modifying time perspective would reduce age differences. Findings provide qualified support for each of these predictions.     

Discrimination and Puerto Rican children's and adolescents' mental health

Two studies of Puerto Rican youths' development on the U.S. mainland examined the consequences of perceived racial/ethnic discrimination on mental health. In Study I, children were found to have a low likelihood of perceiving discrimination, whereas in Study 2, nearly half of the adolescent sample reported perceiving racial/ethnic discrimination. Although both groups scored high on multiple indicators of mental health, perceiving discrimination and worrying about discrimination were negatively associated with some dimensions of self-esteem and positively associated with depression and stress. Adolescents were aware of negative stereotypes about Puerto Ricans, and nearly half of them related discriminatory instances. Results suggest that both perceiving discrimination and anxiety regarding discrimination can serve as risk factors for the mental health of this population.     

Introduction to the special section on Resources for Enhancing Alzheimer's Caregiver Health (REACH)

This article provides background information and an overview on Resources for Enhancing Alzheimer's Caregiver Health (REACH) a multisite intervention trial for caregivers of persons with Alzheimer's disease designed to reduce caregiver burden and depression. REACH is the largest randomized controlled clinical trial to date, involving 1,222 caregiver and care recipient dyads recruited from 6 different sites in the United States. The authors describe the design of the study, summarize the interventions implemented at each site, and provide an overview of the 4 articles in this special section.     

Psychometric analysis of the Revised Memory and Behavior Problems Checklist: factor structure of occurrence and reaction ratings

A modified version of the Revised Memory and Behavior Problems Checklist (RMBPC; L. Teri et al., 1992) was administered across 6 different sites to 1,229 family caregivers of community-dwelling adults with dementia. The total sample was divided randomly into 2 subsamples. Principal components analyses on occurrence responses and reaction ratings from the first subsample resulted in a 3-factor solution that closely resembled the originally proposed dimensions (memory-related problems, disruptive behaviors, and depression). Confirmatory factor analyses on data from the second subsample indicated adequate fit for the 3-factor model. Correlations with other caregiver and care-recipient measures supported the convergent and discriminant validity of the RMBPC measures. In addition, female caregivers and White caregivers reported more problems, on average, than male caregivers and African American caregivers, respectively.     

What do children do in the rime-analogy task? An examination of the skills and strategies used by early readers

Despite the intense debate surrounding the use of orthographic analogy in the clue word paradigm, little is known about the skills and strategies children actually use and how these compare with their everyday reading of single words. This study, with 4- and 5-year-olds (N=125), supports previous work which suggests children rely on phonological, rather than orthographic, priming in the clue word task since children most frequently produced rhyming words in response to the clue word. The extent to which phoneme and rhyme-based skills, along with letter-sound knowledge, predicted children's performance in the analogy task and in a test of single word reading was contrasted and compared. Our findings suggested that the balance of skills which children drew upon was determined by the demands of the task. The implications of these findings for the validity of the 'orthographic'-analogy task and for teaching beginning readers is discussed.     

Development of frontal electroencephalogram (EEG) and heart rate (ECG) responses to affective musical stimuli during the first 12 months of post-natal life

We examined the development of infants' regional electrocortical (EEG) and heart rate (ECG) responses to affective musical stimuli during the first 12 months of post-natal life. Separate groups of infants were seen at 3 (n=33), 6 (n=42), 9 (n=52), and 12 (n=40) months of age at which time regional EEG and ECG responses were continuously recorded during a baseline condition and during the presentation of three orchestral pieces that were known to vary in affective valence and intensity (happy, sad, fear). Overall, there were two important findings. First, we found that although the overall amount of EEG 4-8 Hz power increased between 3 and 12 months, the distribution of EEG power changed across age, with the younger infants (3- and 6-month-olds) showing no difference between frontal and parietal regions, but the older infants (9- and 12-month-olds) showing relatively more activation at frontal than at parietal sites. This development likely reflects the maturation of frontal lobe function. Second, we found that the presentation of affective music significantly increased brain activity at 3 months of age, had seemingly little effect at 6 and 9 months, and significantly attenuated brain activity at 12 months. Findings suggest that there is a clear developmental change in the effect of music on brain activity in the first year, with music having a "calming" influence on infants by the end of the first year of life.
