Assessing the factorial invariance of Harter's self-concept measures: comparing preadolescents with and without spina bifida using child,parent, and teacher report

The purpose of this study was to determine whether the structure of children's self-concept, as rated by children themselves on the Self-Perception Profile for Children (SPPC; Harter, 1985), and the structure of children's competence, as rated by their parents on the Rating Scale of Child's Actual Behavior (PRS) and teachers on the Rating Scale of Child's Actual Behavior (TRS; Harter, 1985), are similar across samples of children with and without spina bifida (children were 8 and 9 years of age; n = 68 in each sample). Using confirmatory factor analyses, results revealed that a multidimensional model for the SPPC and the TRS fit the data well for both samples. On the other hand, the model for both mothers' and fathers' PRS ratings did not fit the data for the spina bifida sample. Further tests of factorial invariance conducted on the SPPC and TRS revealed that the spina bifida and able-bodied samples tended to have the same pattern and magnitude of factor loadings for both instruments. There was some invariance, however, in the amount of unique error variance accounted for across samples. These results bolster our confidence in using the SPPC and TRS to compare children with and without spina bifida.     

Flanker and negative flanker effects in letter identification

In a speeded choice reaction time task, responses to centrally presented letter targets can be altered by the identity of surrounding task-irrelevant letters (flankers). In the standard flanker effect, flankers associated with the same response as the target lead to faster and more accurate responses, whereas flankers associated with a different response lead to slower and more error-prone responses. B. A. Eriksen and C. W. Eriksen (1974, pp. 143-149) have argued that these flanker effects occur through response competition. We present data from a novel version of the Eriksen task, in which some targets and flankers consist of letter forms that are morphed versions of target letters. In this paradigm, flankers induce classic flanker effects on well-formed targets. But flankers induce an opposite effect, termed a negative flanker effect on morphed letter targets. For example, targets that are morphs between the letters "A" and "H" are more likely to be identified as an "A" when flanked by an "H." The interpretation advanced here is that there are two distinct kinds of flanker effects contrast enhancement in perceptual processes and response competition in response selection processes.     

Selective influence through conditional independence

Let each of several (generally interdependent) random vectors, taken separately, be influenced by a particular set of external factors. Under what kind of the joint dependence of these vectors on the union of these factor sets can one say that each vector is selectively influenced by “its own” factor set? The answer proposed and elaborated in this paper is: One can say this if and only if one can find a factor-independent random vector given whose value the vectors in question are conditionally independent, with their conditional distributions selectively influenced by the corresponding factor sets. Equivalently, the random vectors should be representable as deterministic functions of “their” factor sets and of some mutually independent and factor-independent random variables, some of which may be shared by several of the functions.     

Children's working-memory processes: a response-timing analysis

Recall response durations were used to clarify processing in working-memory tasks. Experiment 1 examined children's performance in reading span, a task in which sentences were processed and the final word of each sentence was retained for subsequent recall. Experiment 2 examined the development of listening-, counting-, and digit-span task performance. Responses were much longer in the reading-and listening-span tasks than in the other span tasks, suggesting that participants in sentence-based span tasks take time to retrieve the semantic or linguistic structure as cues to recall of the sentence-final words. Response durations in working-memory tasks helped to predict academic skill and achievement, largely separate from the contributions of the memory spans themselves. Response durations thus are important in the interpretation of span task performance.     

What predicts adjustment among law students? A longitudinal panel study

Although at the time of this article's publication, many anecdotes and cross-sectional studies had reported that law students experience significant distress during their 1st year, few researchers had controlled for prelaw school status (e.g., M. Garrison, B. Tomko, & I. Yip, 1996; L. Guinier, M. Fine, J. Balin, A. Bartow, & D. L. Stachel, 1994), and only a single group of researchers had explored a psychosocial factor that predicted these changes. The present authors tested 3 sets of potential predictors of adjustment: sources of stress, coping strategies, and relationship factors. The present data replicated declines in students' psychological health, physical health, and attitudes toward law over the 1st year of school. That result supports the generalizability and currency of previous studies. In contrast to other researchers, the present authors found few gender differences. Less relationship happiness, less emotional support, and use of less active coping tactics at the beginning of the year predicted poorer outcomes at the end of the year. Strain from academic pressures, lack of personal time, and social isolation were correlated with poorer outcomes.     

Sex differences in recall of real or nonsense words

Women perform better than men on tests of verbal memory, but the nature of this advantage has not been precisely established. To examine whether phonemic memory is a factor in the female advantage, we presented, along with other verbal memory tasks, one containing nonsense words. Overall, there was the expected female advantage. However, an examination of the individual tests showed female superiority in recall of the real words but not the nonsense words.     

Pragmatic versus form-based accounts of referential contrast: evidence for effects of informativity expectations

Characterizing the relationship between form-based linguistic knowledge and representation of context has long been of importance in the study of on-line language processing. Recent experimental research has shown evidence of very rapid effects of referential context in resolving local indeterminacies on-line. However, there has been no consensus regarding the nature of these context effects. The current paper summarizes recent work covering a range of phenomena for which referential contrast has been shown to influence on-line processing, including prenominal and postnominal modification, focus operators, and intonational focus. The results of the body of work suggest that referential context effects are not limited to situations in which the linguistic form of the utterance directly specifies the point of contact with context. Rather, context effects of a pragmatic, Gricean nature appear to be possible, suggesting the relationship between linguistic form and context in rapid on-line processing can be of a very indirect nature.     

Gender Stereotypes in Japanese Television Advertisements

The aim of this study was to reveal gender portrayal types in Japanese television advertisements through content analysis. Five hundred and thirty-one adult main characters were coded for sex, age, ethnic background, credibility, role, place, dress, background, persuasion type, camera work, camera angle, product type, target, and sex of voice-over. Five types were found by performing quick cluster analysis: beautiful and wise housewives, young ladies attracting people's attention, young celebrities, middle- and old-aged people enjoying private time, and middle-aged worker bee. The first three were mainly women and the latter two were mainly men. The results indicate that in Japanese television advertisements men and women are portrayed differently, and the differences correspond with traditional gender stereotypes.     

Affective, behavioral, and cognitive functioning in adolescents with multiple suicide attempts

The purpose of this study was to examine affective, behavioral, and cognitive functioning in adolescents with multiple suicide attempts. Forty-seven adolescents with a history of multiple suicide attempts (MA) were compared to 74 single suicide attempters (SA) on psychiatric diagnosis, depressive symptoms, affect regulation, self-mutilation, alcohol use, and hopelessness. Results revealed that the MA group was more likely to be diagnosed with a mood disorder, and reported more severe depressive symptoms and anger, in comparison to the SA group. Behaviorally, the MA group had higher rates of disruptive behavior disorders and higher levels of affect dysregulation and serious self-mutilation than the SA group. Further, greater levels of hopelessness were reported by the MA than the SA group. After controlling for a mood disorder diagnosis, only differences in anger, affect dysregulation, and serious self-mutilation remained significant. Overall, results suggest that treatment with adolescent suicide attempters might specifically target anger and affect dysregulation to reduce risk for future suicidal behavior.
