Action experience alters 3-month-old infants' perception of others' actions

An intervention facilitated 3-month-old infants' apprehension of objects either prior to (reach first), or after (watch first) viewing another person grasp similar objects in a visual habituation procedure. Action experience facilitated action perception: reach-first infants focused on the relation between the actor and her goal, but watch-first infants did not. Infants' sensitivity to the actor's goal was correlated with their engagement in object-directed contact with the toys. These findings indicate that infants can rapidly form goal-based action representations and suggest a developmental link between infants' goal directed actions and their ability to detect goals in the actions of others.     

Bivalency is costly: bivalent stimuli elicit cautious responding

When performing tasks in alternation, substantial slowing occurs when the stimuli have features relevant to both tasks (i.e., when stimuli are bivalent as opposed to univalent). One possible source of this slowing, herein called a bivalency cost, is that encountering bivalent stimuli leads to a more cautious response style. To investigate this, we employed a paradigm that required performing three simple tasks, with bivalent stimuli occasionally encountered on one task. The results show that regardless of the feature overlap among the stimuli used for the different tasks, the introduction of bivalent stimuli slowed responding on all tasks and it was accompanied by a decrease in response errors. Overall, it appears that bivalent stimuli recruit a more cautious approach to task-switching performance.     

Rural adolescent loneliness and coping strategies

The extent of loneliness of rural adolescents was investigated in relation to aspects of their self-esteem. The study sample consisted of 387 4-H children from rural Nebraska ranging in age from 8 to 20 years. Data were gathered using the Loneliness Inventory (Woodward, 1967), Bachman's (1970) Self-Esteem Scale, and the Coping Strategies Inventory (Woodward, 1987). It was found that rural adolescents have extremely high loneliness scores and that 10 of 12 self-esteem characteristics were significant at the .05 level in relation to loneliness scores. Resources and coping strategies used by the subjects to combat loneliness are provided and implications of the findings discussed.     

Childhood Peer Relationship Problems and Psychosocial Adjustment in Late Adolescence

Using prospective longitudinal data from the Christchurch Health and Development Study, this paper examined the relationship between teacher reported peer relationship problems at age 9 and psychosocial adjustment in late adolescence. Results showed that, by age 18, children with high rates of early peer relationship problems were at increased risk of externalizing behavior problems such as criminal offending and substance abuse, but were not at increased risk of anxiety disorder or major depression. Subsequent analyses revealed that these associations were largely explained by the effects of child and family factors associated with both early peer relationship problems and later adjustment. The most influential variable in explaining associations between peer relationship problems and later adjustment was the extent of children's early conduct problems. These results suggest that reported associations between early peer problems and later adjustment are noncausal, and appear to reflect underlying continuities in behavioral adjustment.     

Videodisc instruction in science and mathematics: Implications for media research and instructional design

This article summarizes research conducted over the last seven years on videodisc instruction in science and mathematics. Research findings, as well as the instructional design principles used to create programs, have direct implications for the general debate over media and its effects on learning. The array of studies conducted with the videodisc programs indicates that the medium is very cost effective. High quality instruction can be presented reliably and with much less human effort than traditional methods of instruction. By using videodiscs, developers are also able to exploit the strong graphic features of the medium, thus allowing carefully-designed visual images to play a key role in the instruction. Empirical support for non-text presentations along with examples of the graphics used in the science and mathematics programs are discussed.     

Word-to-word variation in ERP component latencies: spoken words

Data were collected shedding light on the brain electrical activity underlying word recognition. Subjects listened to a list of 48 spoken words in six random orders under two instructional sets: first to "think about the meanings of the words," and second, to learn the list. The scalp EEG associated with hearing and identifying the words was recorded at F3, F4, Cz, P3, P4, Pz, and Oz. Standard within-subjects time-locked averaging across words showed a late negative-positive complex with N2-P3 topography, the negative component peaking around 480 msec, the positive component peaking around 830 msec. Averaging within words across subjects uncovered considerable latency variability in both components. Within-word N2 and P3 component latencies covaried with word durations and with the "recognition points" predicted for the words by the "cohort theory" of word recognition. N2 latencies corresponded closely to the "N400" effect elicited with semantically incongruous sentence-final spoken words. Implications for ERP investigations of language processing are discussed.     

Cognitive restructuring treatment: A controlled trial with anxious patients

Cognitive restructuring, modified systematic desensitization and a combined treatment (cognitive behaviour modification) were compared with a no-treatment control group, using a simple randomized design. Twenty seven general anxiety out-patients selected from the hospital waiting list were used as subjects. Assessments were made at the beginning and end of treatment, and at follow-up 1 month later. The assessments included two subjective anxiety measures, the Zung self-rating anxiety scale and fear thermometer scores, a behavioural anxiety measure, a measure of cognitive anxiety as estimated by a diary recording of thinking time, fear survey schedule scores and I/E scores.Cognitive behaviour modification was found to be a superior form of treatment, relative to the no-treatment control and the other active treatment groups as assessed by FSS intensity score. The cognitive behaviour modification group showed greater improvement than the cognitive restructuring group on the diary anxiety scores. The results also demonstrated a relationship between outcome and initial severity of condition. The higher the subjects' initial scores on neurotic symptoms and subjective anxiety level, the greater the degree of positive change after treatment. Moreover, subjects with high levels of internal control prior to treatment responded most to therapy.     

How to be a successful psychotherapist no matter what the effect on behavior: the corn soup principle

An accidental discovery in a Hospital Cafeteria led to the formulation of non-therapeutic intervention. This paper describes how therapy may be successful for the therapist, independent of changes in the client.     

Sex differences in adjustment correlates of locus of control dimensions

This study investigated the hypothesis that dimensions of locus of control are differentially predictive of adjustment criteria for males and females. Two samples of undergraduates completed the Reid-Ware Three-Factor Locus of Control Scale and either the Texas Social Behavior Inventory or the Zander and Thomas version of the Barron ego strength scale. For both males and females, internals reported greater self-esteem and ego strength. However, for males, the fatalism dimension was the strongest predictor for each adjustment correlate. The social system control dimension was not predictive for males in either case. For females, the social system control dimension was predictive for each adjustment correlate, although it was not consistently the strongest predictor. The results are consistent with research on sex differences in parental antecedents of locus of control. Methodological implications of the differential predictiveness of locus of control dimensions are also addressed.
