Precursors to infants'' perception of the causality of a simple event

Three habituation experiments examined the perception of causal and non-causal events by infants at 6 1/4, 5 1/2, and 4 months of age. Experiment 1 replicated previous studies showing that by 6 1/4 months, infants begin to respond to the interaction of simple objects in Michottian type launching events on the basis of causality. In Experiments 2 and 3, however, younger infants exposed to the identical event sequences responded on the basis of simpler perceptual features of the launching events, and not on the basis of causality. 4-month-old infants responded to continuous versus non-continuous movement. 5 1/2-month-old infants also responded somewhat on the basis of continuous movement. However, in addition they responded on the basis of the spatial and temporal perceptual features of the events. This change in the pattern of results over age suggests a multi-step developmental progression.     

Job Interview Strategies For People with a Visible Disability1

A total of 117 students participated in the present investigation, which compared wheelchair-user and able-bodied job applicants as well as two interview-taking strategies available to wheelchair users: disclosing the disability during the telephone screening or not doing so and acknowledging it only during a face-to-face interview. Results show that wheelchair-user applicants were evaluated more favorably than able-bodied applicants during the telephone interview, a finding consistent with the positivity bias and “sympathy effect” findings of others. After a face-to-face interview, wheelchair-user applicants who did not disclose their disability over the telephone were evaluated somewhat more favorably than those who did so. However, they were less likely to be selected for the job. The implications of the results for theory, research, and practice are discussed.     

Trait Attributions About College Students With a Physical Disability: Circumplex Analyses and Methodological Issues1

Trait attributions concerning able-bodied college students and those with a physical disability were investigated in two studies. In Study 1, 194 able-bodied students completed extensive adjective checklists in one of four experimental conditions: stimulus person physically disabled (wheelchair user) male, disabled female, able-bodied male, or able-bodied female college student. To avoid self-presentation biases, subjects completed checklists not in terms of their own views but in terms of commonly held stereotypes. Results showed that not only were fewer socially desirable and more undesirable traits attributed to students with a disability than to able-bodied students, but when tested for “sameness” vs. “oppositeness” using two circumplex models, traits attributed to students who have a disability were clearly the “opposite” of those attributed to able-bodied students. In Study 2, 115 students completed a trait checklist based on the findings of Study 1 with reference to one of the four stimulus persons. Although subjects reported their own views, the results were consistent with those of Study 1. It was also found that stereotyping in the socially desirable direction was related to stereotyping in the undesirable direction; both were related to lack of ease with students with a disability. Common stereotypes of wheelchair user students are listed and the implications of the findings for the design of programs to reduce prejudice and integrate students with a disability into academic life are discussed.     

Ethnic Identity and Discrimination: An Exploration of the Rejection-Identification Model in Arab American Adolescents

Research examining the rejection-identification model of ethnic identity in Arab American adolescents is scarce. This exploratory study investigates various factors in relation to a sample of 60 Arab American adolescents’ (aged 12–18 years) ethnic identity including discrimination and academic and global self-concepts. Ethnic identity was measured using the Multigroup Ethnic Identity Measure, which is composed of two factors including Affirmation/Belonging and Ethnic Search. The Self-Perception Profile for Adolescents was used to measure academic and global self-concepts. In addition, the lead author developed a questionnaire asking participants to self-report whether either they or another Arab student they knew had been treated badly or differently because of their ethnicity. Discrimination experience and Affirmation/Belonging were significant predictors of scholastic competence, while Affirmation/Belonging was the sole significant predictor in Global Self-Worth. High levels of ethnic identity in the area of Affirmation/Belonging seemed to play a protective role in global self-concept in the face of discrimination. Implications and directions for future research are discussed.     

Predictive and concurrent validity of the Suicidal Ideation Questionnaire among American Indian adolescents

Suicide is currently the second leading cause of death for ages 15–24 years; reports indicate that 6–8% of American teens have attempted suicide. Rates of suicide and suicide attempts are at least as high, if not higher, for American Indian adolescents and young adults. The Suicidal Ideation Questionnaire (Junior High School Version) (SIQ-JR) could be used to identify young people who may be at risk for attempting suicide, since this questionnaire focuses on suicidal ideation, a major risk factor for suicide attempt. However, little is known about the predictive validity of the SIQ-JR, particularly in American Indian adolescent populations. A suicide attempt cluster at an American Indian boarding school provided the unique opportunity to examine the performance of the SIQ-JR in a group of American Indian high school students who had taken the SIQ-JR approximately 2 months prior to the outbreak of attempts. The SIQ-JR proved to be an excellent predictor of future suicide attempts when compared to other measures of distress: anxiety, depression, and alcohol use. The SIQ-JR is an effective screener for suicide risk in this American Indian adolescent population.     

How the personality dimensions of neuroticism, extraversion and psychoticism relate to self-actualization

This study examines the relationship between the personality dimensions of ‘neuroticism’, ‘extraversion’, ‘psychoticism’, from the Eysenck Personality Questionnaire (EPQ) and ‘self-actualization’, measured by the Personal Orientation Inventory (POI) for 212 undergraduate students. The two major scales of the POI, (Time Competence and Inner Directed), both separately and as a combined measure of self-actualization were correlated with the scores obtained on the EPQ. The results showed the hypothesized significant negative relationship between neuroticism and self-actualization, and for females only, the hypothesized significant positive relationship between extraversion and self-actualization. Contrary to hypothesis, no relationship between psychoticism and self-actualization was found.     

Preservation of orthographic knowledge in aphasia

A simple untimed lexical decision task was designed to test implicit letter recognition in aphasic patients. Half of the nonwords used in this task were orthographically regular pronounceable pseudowords, and half were orthographically irregular unpronounceable letter strings. Twenty-five randomly chosen aphasic patients with mild to severe degrees of aphasia participated in the study. Although only six of the patients performed the lexical decision task successfully, all 25 demonstrated the ability to distinguish orthographically regular from irregular letter strings and, by implication, the ability to recognize and make use of the identities of written letters.     

Effect of interpolated extinction after partial delay of reward training on subsequent reacquisition and extinction

Four groups of albino rats were run four trials a day in a straight runway for 44 days. On the first 15 days, two groups were given continuous immediate reward (IR) and two groups a 50 per cent, schedule of 30-sec. partial delay of reward (PDR). On the next 15 days, one IR group and one PDR group were extinguished, while the other IR and PDR groups remained on their original schedules. In the third phase, all groups received 8 days of training on IR. Finally, all groups were given 6 days of extinction training. In the first extinction, PDR produced greater resistance to extinction than IR. In the second extinction period, the PDR group which had previously been given extinction and the two IR groups extinguished relatively rapidly and at approximately the same rates, while the PDR group which had not been extinguished was significantly more resistant to extinction than the other three groups.     

A dual-process account of the development of scientific reasoning: The nature and development of metacognitive intercession skills

Metacognitive knowledge of the dual-processing basis of judgment is critical to resolving conflict between analytic and experiential processing responses [Klaczynski, P. A. (2004). A dual-process model of adolescent development: Implications for decision making, reasoning, and identity. In R. V. Kail (Ed.), Advances in child development and behavior, Vol. 31 (pp. 73–123). San Diego, CA: Academic Press]. Such conflict is ubiquitous when reasoning scientifically. Three studies explored the nature, development, and stability of this metacognitive knowledge. In each study, participants completed the ratio-bias judgment task, which assessed their tendency to make analytically based responses, and the ratio-bias evaluation task, which assessed their metacognitive knowledge of the processing basis of judgments on the task (Metacognitive Status). In Study 1, college students’ judgment performance was related to metacognitive status but not to general cognitive ability. In Study 2, metacognitive status was related to age and mathematics-related changes. Metacognitive status again predicted participants’ tendency to make analytically based judgments. In Study 3, college students’ judgments, but not metacognitive status, were affected by task conditions. The evidence suggests that assessing metacognitive knowledge is important for understanding how conflict between analytically and experientially based judgments is resolved.
