Children's attitudes toward peers with disabilities: the Israeli perspective

Attitudes toward peers with disabilities were compared in two groups of elementary school children, Israeli (2845 children) and Canadian (1831 children), using the Chedoke-McMaster Attitudes Toward Children with Handicaps (CATCH) scale. Israeli children expressed significantly more positive general attitudes (P=0.0001). The more favourable attitudes were seen in both areas evaluated by the CATCH, the cognitive and the affective-behavioural. In both groups, children who had had previous experience with a disabled person expressed more positive attitudes (P=0.001). An effect of gender was seen in the Canadian but not in the Israeli children. Cultural factors appear to play a role in modelling children's attitudes toward their disabled peers and therefore should be considered before educational programmes are implemented.     

Congruency, attentional set, and laterality effects with emotional words.

The present study investigated the influence of attention and word-emotion congruency on auditory asymmetries with stimuli that include verbal and emotional components. Words were presented dichotically to 80 participants and were pronounced in either congruent or incongruent emotional tones. Participants were asked to identify the presence of a target word or emotion under 1 of 2 conditions. The blocked condition required detection of a word or emotional target in separate blocks. In the randomized condition, the target was changed across trials by means of a postcue. A right-ear advantage (REA) and a left-ear advantage (LEA) were found for word and emotion targets, respectively. However, the finding of a Condition × Stimulus Type × Ear × Congruency interaction indicated that in the randomized condition, a REA was obtained for words when the stimuli were congruent and a LEA was observed for emotions when the stimuli were incongruent. The findings suggest that randomizing the target reduced the influence of the attentional set established by blocking the target. It is likely that this promoted the detection of hemispheric interference in the randomized condition. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Self-awareness, task failure, and disinhibition: how attentional focus affects eating

Prolonged continuous blood pressure (BP) and heart rate (HR) recordings from neonates of 35 to 42 weeks gestation were studied during and after ECMO. Data segments with significant deviation of BP were extracted for further analysis. The simultaneous changes in BP and HR were compared and the slope of the regression determined baroreflex sensitivity (BRS). Of 464 BP deviations, 98% produced curves with a negative slope consistent with the presence of a baroreflex. The average BRS was -1.0 +/- 0.8 bpm/mmHg (mean +/- S.D.) and curves were steeper during rising BP than falling BP (-1.1 +/- 0.9 beats/min per mmHg versus -0.9 +/- 0.6, P = 0.001). The baroreflex was more sensitive during ECMO than after ECMO to both rising BP (-1.0 +/- 0.5 beats/min per mmHg versus -0.7 +/- 0.5, P = 0.004) and falling BP (-1.0 +/- 0.6 beats/min/mmHg versus -0.7 +/- 0.5, P = 0.04). HR response curves obtained during different BP fluctuations on the same recording had varying threshold, consistent with acute resetting. One infant demonstrated chronic baroreceptor resetting over 3 days to a rise in resting BP. The near-term, critically ill neonate has an active baroreflex which is capable of resetting. ECMO was associated with accentuation of the baroreflex response.     

The effects of an elaborated goal on the persuasive writing of students with learning disabilities and their normally achieving peers.

Fourth- and sixth-grade students with and without learning disabilities (LD) wrote persuasive essays about controversial topics under 2 different conditions. Students in the general goal condition were asked to write a letter to persuade an audience to agree with their position. Students in the elaborated goal condition were given the same general goal plus explicit subgoals based on the elements of argumentative discourse. Sixth-grade students in the elaborated goal condition produced more persuasive essays and included a greater number of argumentative elements in their essays than did either 6th graders in the general goal condition or 4th graders in both goal conditions. In addition, students with LD wrote less persuasively than did their normally achieving peers. Implications for the study of argumentative writing are discussed.

Children's attributions for success and failure: Effects of age and attentional focus.

This study was an assessment of how children's achievement attributions were influenced by their age, attentional focus, gender, and success or failure experience. Older and younger elementary school children performed a memory task under either self-focusing or task-focusing instructions. After performance, half of the children in each condition were given success feedback and the other half failure feedback. Attributions for performance were then obtained. In the success condition, children judged effort to be the most important cause of their performance, whereas children in the failure condition attributed their performance mostly to the difficulty of the task and their inability to remember the story. Older children in the self-focus condition attributed success more to internal causes than did older children in the task-focus condition. Younger children attributed both success and failure more to luck than did older children. Few sex differences in attributions were obtained.

Revisiting the novelty effect: When familiarity, not novelty, enhances memory.

Reports of superior memory for novel relative to familiar material have figured prominently in recent theories of memory. However, such novelty effects are incongruous with long-standing observations that familiar items are remembered better. In 2 experiments, we explored whether this discrepancy was explained by differences in the type of familiarity under consideration or by differences in the difficulty of discriminating targets from lures, which may lead to source confusion for familiar but not novel targets. In Experiment 1, we directly tested whether previously observed novelty effects were the result of novelty, discrimination demands, or both. We used linguistic materials (proverbs) to replicate the novelty effect but found that it occurred only when familiar items were subject to source confusion. In Experiment 2, to examine better how novelty influences episodic memory, we used experimentally familiar, pre-experimentally familiar, and novel proverbs in a paradigm designed to overcome discrimination demand confounds. Memory was better for both types of familiar proverbs. These results indicate that familiarity, not novelty, leads to better episodic memory for studied items, regardless of whether familiarity is experimentally induced or based on prior semantic knowledge. We argue that proposals that state that information is encoded better if it is novel are based on over-generalizations of effects arising from the distinctiveness of novel materials.

Role of attentional focus in pain perception: Manipulation of response to noxious stimulation by instructions.

Studied the effects of instructions on the pain induced by cold as a noxious stimulus in 18 male and 18 female paid volunteers. Pain threshold and quit point were obtained for 3 groups of Ss. Group I dissociated their experience of cold and pain, and focus on cold. Group II focused on cold and interpreted it as pleasant. Group III served as controls. Significant elevation in pain threshold (but not quit point) was found in both instruction groups. Males showed greater elevation in threshold than females in response to the instructions. Sex differences and response bias are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Neonatal handling and environmental enrichment effects on emotionality, novelty/reward seeking, and age-related cognitive and hippocampal impairments: focus on the Roman rat lines

Roman high- and low-avoidance (RHA/Verh and RLA/Verh) rats are selected and bred for extreme divergence in two-way active avoidance acquisition. In addition, compared to RLA/Verh rats, RHA/Verh rats are (behaviorally and physiologically) less anxious or reactive to stressors, show increased novelty (sensation)-seeking behavior as well as a higher preference for rewarding substances, and are usually less efficient in learning tasks not involving shock administration. The present article reviews evidence showing that neonatal handling and/or environmental enrichment leads to enduring effects (their magnitude frequently depending upon the rat line) on those behaviors. For example, it has been found that neonatal handling reduces most of the (behavioral and physiological) signs of emotionality/anxiety in RLA/Verh rats, while environmental enrichment increases their novelty seeking (also the case with RHA/Verh rats), saccharin and ethanol intake, and sensitivity to amphetamine. Finally, initial results (currently being further elaborated upon) support a preventive action of both environmental treatments on age-related impairments in learning a spatial, water maze task as well as on hippocampal neuronal atrophy.     

Focal distraction: Spatial shifts of attentional focus are not required for contingent capture.

Contingent capture occurs when distractors that share the target's defining attribute capture attention and slow down target identification. This slowdown has been attributed to an involuntary attentional shift to the location of a pertinent distractor. The present study examined an additional source of delay: the time spent in processing pertinent distractors. In 7 experiments, distractors were presented at fixation, and targets were presented either at fixation or peripherally. Contingent capture invariably occurred when a salient distractor was presented within about 600 ms before the target, even when spatial shifts in attentional focus were ruled out. A 2-stage model is proposed in which stimuli must pass an input filter tuned to the target's defining attribute before gaining access to a high-level stage that is unavailable while a distractor is being processed.

Personality and verbal conditioning effects.

In line with the studies on the conditioning of verbal behavior and their reference to psychotherapy, the present study investigates the effects of Autonomy (as measured by the EPPS) upon verbal conditioning. The hypothesis was made that Autonomy would interfere with susceptibility to verbal conditioning. Ss were interviewed, being asked to talk about themselves; E reinforced (said "um-hmm" and nodded head) under 3 conditions, viz., when S made positive self-statements, negative self-statements, or reinforced randomly throughout the interview. The results indicate that by responding selectively, an interviewer can influence the verbalization of S; in this instance, reinforcement was effective in producing a significant effect on positive self-statements, but not negative ones. Meaning of results are discussed with relation to other research and an attempted formulation. From Psyc Abstracts 36:01:3CJ41B. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Transactive discussions with peers and adults.

Piaget (1932) hypothesized that peer and adult–child discussions of moral dilemmas are qualitatively different and that children are more likely to use reasoning when interacting with peers. To test this hypothesis, the present study compared the interactive styles of child–child and adult–child dyads engaged in discussions of moral dilemmas, focusing on the use of logical operations (transacts). 48 7- and 11-yr-old girls were paired with either a female agemate or their mother. Ss used transacts in a higher proportion of their conversational turns when interacting with peers than when interacting with mothers. Ss produced proportionally more transactive responses when interacting with mothers because mothers produced proportionally more requests for idea clarification than did peer partners. Self-generated transacts, on the other hand, were produced proportionally more often with peers. When paired with peers, Ss produced transactive statements that operated on the partner's logic more often rather than clarifying their own logic. Results support Piaget's contention that moral discussions with peers feature a more spontaneous use of reasoning than do discussions with adults.

The effects of patients' relationships with peers and staff on their psychiatric treatment.

Determinants and effects of attentional bias in smokers.

Much research has shown that individuals exhibit an attentional bias to stimuli related to their current concerns or pathologies. Using the emotional Stroop task, we investigated attentional bias in smokers. Ninety-six smokers either abstained from smoking for 24 hrs or smoked normally before color-naming smoking-related and neutral words. Both a blocked format (smoking and neutral words presented in separate blocks) and an unblocked format (smoking and neutral words presented in a mixed random sequence) were used. In the blocked format, abstinence caused an attentional bias to smoking-related stimuli, and the degree of attentional bias predicted the latency to the first cigarette of the morning. However, different results were obtained from the unblocked version of the task. We conclude that the emotional Stroop task is a useful tool to measure attentional bias in smokers and could be used in cessation studies.

Affiliation with antisocial peers, susceptibility to peer influence, and antisocial behavior during the transition to adulthood.

Developmental theories suggest that affiliation with deviant peers and susceptibility to peer influence are important contributors to adolescent delinquency, but it is unclear how these variables impact antisocial behavior during the transition to adulthood, a period when most delinquent individuals decline in antisocial behavior. Using data from a longitudinal study of 1,354 antisocial youth, the present study examined how individual variation in exposure to deviant peers and resistance to peer influence affect antisocial behavior from middle adolescence into young adulthood (ages 14 to 22 years). Whereas we find evidence that antisocial individuals choose to affiliate with deviant peers, and that affiliating with deviant peers is associated with an individual’s own delinquency, these complementary processes of selection and socialization operate in different developmental periods. In middle adolescence, both selection and socialization serve to make peers similar in antisocial behavior, but from ages 16 to 20 years, only socialization appears to be important. After age 20, the impact of peers on antisocial behavior disappears as individuals become increasingly resistant to peer influence, suggesting that the process of desistance from antisocial behavior may be tied to normative changes in peer relations that occur as individuals mature socially and emotionally.

Self-esteem, construal, and comparisons with the self, friends, and peers.

Extending the better than average effect, 3 studies examined self-, friend, and peer comparisons of personal attributes. Participants rated themselves as better off than friends, who they rated as superior to generalized peers. The exception was in direct comparisons, where the self and friends were not strongly differentiated on unambiguous negative attributes. Self-esteem and construal played moderating roles, with persons with high self-esteem (HSEs) exploiting both ambiguous positive and ambiguous negative traits to favor themselves. Persons lower in self-esteem exploited ambiguous positive traits in their favor but did not exploit ambiguous negative traits. Across self-esteem level, ratings of friends versus peers were exaggerated when attributes were ambiguous. HSEs seemed to take advantage of ambiguity more consistently to present favorable self-views; people with low self-esteem used ambiguity to favor their friends but were reluctant to minimize their own faults.

Blinks of the mind: Memory effects of attentional processes.

If 2 words are presented successively within 500 ms, subjects often miss the 2nd word. This attentional blink reflects a limited capacity to attend to incoming information. Memory effects were studied for words that fell within an attentional blink. Unrelated words were presented in a modified rapid serial visual presentation task at varying stimulus-onset asynchronies, and attention was systematically manipulated. Subsequently, recognition, repetition priming, and semantic priming were measured separately in 3 experiments. Unidentified words showed no recognition and no repetition priming. However, blinked (i.e., unidentified) words did produce semantic priming in related words. When, for instance, ring was blinked, it was easier to subsequently identify wedding than apple. In contrast, when the blinked word itself was presented again, it was not easier to identify than an unrelated word. Possible interpretations of this paradoxical finding are discussed.

Stress, anxiety, and cognitive interference: Reactions to tests.

Analyzed the nature of test anxiety and its relationships to performance and cognitive interference from the standpoint of attentional processes. A new instrument to assess dimensions of reactions to tests is presented, and its psychometric properties are described. The scales of the Reactions to Tests (RTT) questionnaire (Worry, Tension, Test-Irrelevant Thinking, Bodily Symptoms) were compared with regard to intellective performance and cognitive interference. In Study 1, 390 undergraduates completed the Test Anxiety Scale (TAS) and responded to 91 items regarding their test reactions. In Study 2, 385 undergraduates completed the Cognitive Interference Questionnaire (CIQ), TAS, the Digit Symbol subscale of the WAIS, and the RTT. In Study 3, 180 undergraduates who had completed the RTT were administered difficult anagrams and the CIQ. Results are consistent with the idea that the problem of anxiety is, to a significant extent, a problem of intrusive thoughts that interfere with task-focused thinking. In the last of the 3 studies reported, it is shown that self-preoccupying intrusive thinking can be reduced by means of a task-focusing experimental condition. The studies suggest that the RTT questionnaire may be useful in defining anxiety more sharply and improving understanding of how it relates to performance.

Competition between the conditioned rewarding effects of cocaine and novelty.

Access to novelty might provide an alternative learning history that competes with conditioned drug reward. We tested this suggestion in rats using a place conditioning procedure with cocaine and novelty. In Experiment 1, rats were conditioned with cocaine to prefer one side of an apparatus. In a subsequent phase, cocaine exposure continued; however, on the unpaired side, separate group of rats had access to novel objects, cocaine injections, or saline with no objects. Pairings with novel objects or cocaine shifted a preference away from the cocaine-paired environment during drug-free and drug-challenge tests. Experiment 2 tested novelty's impact when cocaine exposure was discontinued. The identical procedures were used except drug exposure ceased on the cocaine-paired side during the second phase. Both groups expressed a preference for the cocaine compartment. This preference was maintained for rats that did not have novel objects; however, rats that experienced novelty spent similar amounts of time in both compartments during both tests. Overall, the conditioned rewarding effects of novelty competed with those of cocaine as evidenced by a change in choice behaviors motivated by drug reward.

Children's interpersonal influence with mothers and peers.

Interpersonal influence attempts toward mothers and peers were examined in 75 5-yr-olds. Consistent with a Piagetian view, children were less often immediately successful in their mother-directed attempts than in their peer-directed attempts. However, they were more often able to negotiate a compromise with mothers than with peers. This indicates that interaction with mothers may be more conducive to the development of social competence than interaction with peers. Linkages between both contexts were identified. Children who used abrasive strategies with mothers were aggressive and unsuccessful with peers. Mothers' influence strategies, assessed when children were toddlers and at age 5, predicted children's influence styles with peers: Children whose mothers often used negative control were aggressive and unsuccessful; those whose mothers used polite guidance were rarely inarticulate or coercive; and those whose mothers often issued unclear commands were less successful and less prosocial with their peers.
