Evidence for task conflict in the Stroop effect

C. M. MacLeod and P. A. MacDonald (2000) suggested that congruent and incongruent Stroop stimuli cause more task conflict than neutral stimuli because the anterior cingulate cortex is more activated with these stimuli. This study investigated behavioral expression for this pattern. Experiment 1 reduced task conflict control by increasing the proportion of nonword neutrals. Additionally, half the trials had conflict or neutral cues. The control reduction revealed the task conflict. For noncued trials, response time was longer for congruent stimuli than for neutral stimuli (reverse facilitation effect). In addition, response time for congruent stimuli was longer when stimuli were uncued vs. cued. Experiment 2 increased task conflict control by changing the neutral stimuli to noncolor words. Consequently, the task conflict expression disappeared.     

The Impact of Gender and Age on Attitudes and Reactions to Unemployment: The Israeli Case

The research examined the impact of gender and age on attitudes and reactions to joblessness among 613 unemployed individuals in Israel (aged 21–60 years). With regard to ethnicity, most of the participants were born in Israel and the remainder were evenly distributed between Europe–America and Asia–Africa. The majority of participants had at least secondary education. On the whole, results indicated that both gender and age had significant effects, but did not interact. Furthermore, there was little significant interaction between marital status and gender. Despite recent changes in women's orientations toward work, gender differences are still evident in relation to unemployment: (1) women tend to reject jobs more readily than men on the basis of job content, working conditions, conflicts between job requirements and family obligations, and masculine-typed work, and (2) men tend to devote more time per week to job hunting. As these differences are not age related and are partly independent of marital status, it can be argued that they stem from generalized social expectations regarding gender roles (men as breadwinners and women as responsible for the home) to which unemployed men and women adjust themselves even before they actually fill these roles. In addition, the following age differences were apparent: (1) middle-aged unemployed reported spending more time looking for work than did members of the younger groups, (2) the youngest group saw advantages in unemployment in that it left them time to devote to themselves and also reported the least deterioration in health as a result of unemployment, and (3) young people were more likely to believe that others have no respect for the unemployed, yet preferred to be out of work than to accept a low-paying job.     

A Phenomenological Study of Immigrant Parents of Adolescents with Delinquent Behavior in Israel

Scarce qualitative literature has focused on understanding the perspective of parents of adolescents involved in crime, and no prior literature has examined how the status of being a parent of an adolescent who is involved in delinquency intersects with being an immigrant parent. The current phenomenological study examined, through the eyes of immigrant parents, how they comprehend their children’s involvement in delinquent behavior. This study examined in-depth semistructured interviews conducted with fourteen immigrant parents (10 mothers and 4 fathers) from the former Soviet Union in Israel of children treated in rehabilitation facilities for delinquent youth. Data analysis revealed a gradual decline in children's behavior ascribed to the developmental stage of adolescence, the pressures of immigration, and cultural conflict. These three factors are interwoven together to create a fabric within which they see their children turning to crime. Parents' gradual loss of control is balanced by attempts to idealize the parent–child relationship and to minimize the severity of the offenses committed. They describe various differing and even contradictory experiences of themselves as parents and their struggles to piece together incohesive, alternating experiences of themselves as parents. Despite the critical role they can play in their children’s rehabilitation, as well as the distress that they themselves experience, parents of children involved in delinquent behavior have often been ignored in research. Acknowledging parents' perspectives and experiences can allow development of appropriate therapeutic strategies to support them and maximize their abilities to support their children.     

Psychoacoustic abilities as predictors of vocal emotion recognition

Prosodic attributes of speech, such as intonation, influence our ability to recognize, comprehend, and produce affect, as well as semantic and pragmatic meaning, in vocal utterances. The present study examines associations between auditory perceptual abilities and the perception of prosody, both pragmatic and affective. This association has not been previously examined. Ninety-seven participants (49 female and 48 male participants) with normal hearing thresholds took part in two experiments, involving both prosody recognition and psychoacoustic tasks. The prosody recognition tasks included a vocal emotion recognition task and a focus perception task requiring recognition of an accented word in a spoken sentence. The psychoacoustic tasks included a task requiring pitch discrimination and three tasks also requiring pitch direction (i.e., high/low, rising/falling, changing/steady pitch). Results demonstrate that psychoacoustic thresholds can predict 31% and 38% of affective and pragmatic prosody recognition scores, respectively. Psychoacoustic tasks requiring pitch direction recognition were the only significant predictors of prosody recognition scores. These findings contribute to a better understanding of the mechanisms underlying prosody recognition and may have an impact on the assessment and rehabilitation of individuals suffering from deficient prosodic perception.     

Anger and shame as determinants of perceived competence

Emotions are complex signals conveying a multitude of “messages” concomitantly. This idea is examined within the context of competence inferences drawn from the emotional expressions of another individual. In two studies, participants assuming the role of patients took part in a simulated medical consultation. They encountered a physician who had either a high or a standard professional status, and who responded with anger, shame, or emotional neutrality when asked to clarify the advice he dispensed. While a display of anger did not affect perceived competence, shame made the physician appear less competent. Three types of signals conveyed by the emotions were responsible for these effects: the physician's decisiveness and control over the situation, and the extent to which he felt professionally devalued by the patient's request, mediated the effects of the emotions on perceived competence. A priori information about the physician's professional status had little effect on the perception of competence. The research exemplifies the richness of information contained in emotions, and the complex way in which it allows observers to construe an impression of the expresser.     

The numerical distance effect is task dependent

Number comparison tasks produce a distance effect e.g., Moyer & Landauer (Nature 215: 1519-1520, 1967). It has been suggested that this effect supports the existence of semantic mental representations of numbers. In a matching task, a distance effect also appears, which suggests that the effect has an automatic semantic component. Recently, Cohen (Psychonomic Bulletin & Review 16: 332-336, 2009) suggested that in both automatic and intentional tasks, the distance effect might reflect not a semantic number representation, but a physical similarity between digits. The present article (1) compares the distance effect in the automatic matching task with that in the intentional number comparison task and suggests that, in the latter, the distance effect does include an additional semantic component; and (2) indicates that the distance effect in the standard automatic matching task is questionable and that its appearance in previous matching tasks was based on the specific analysis and design that were applied.     

Word-association responses to time-altered stimuli by schizophrenic adults

This research addressed the relationship between the speed of presentation of stimuli through the auditory and visual modalities and the number of syntagmatic and paradigmatic word-association responses of 49 chronic undifferentiated schizophrenic adults. In word-association tests administered to subjects stimuli were balanced for frequency of occurrence in written English language (frequent, infrequent), word length (long, short), abstraction level (low, medium, high), and part of speech (noun, verb, adjective). The words were presented auditorily at normal speed (equivalent to 10 phonemes per second) and at half speed (equivalent to 5 phonemes per second) speech. Words were also presented visually, using a tachistoscope, at extended fixation speed (equivalent to 1,000 msec.) and at sweep speed (equivalent to 10 msec.). More paradigmatic responses occurred on word stimuli if nouns, long, and frequently occurring presented auditorily; and if concrete, nouns, and presented slowly and visually. Results were compared to previously reported data for aphasic and normal adults, and differentiating features and clinical implications were discussed.     

Characteristic patterns of word association responses in institutionalized elderly with and without senile dementia

This study examined the responses of 91 institutionalized elderly persons to the Goldfarb-Halpern Word Association Test (1981), Journal of Speech and Hearing Research, 24, 233–246. Subjects with senile dementia evidenced a characteristic pattern of responses which included marked reduction of paradigmatic responses, no decrease in syntagmatic responses, and a marked increase in unclassifiable and multiword responses not previously reported in the literature. The declines and increases appeared linear and progressive with severity of dementia. The pattern was distinct from that of any other adult group previously tested with this tool. Institutionalized elderly subjects without senile dementia performed similarly to previously tested noninstitutionalized elderly. Theoretical and clinical implications are discussed.     

First-Order Frege Theory is Undecidable

The system whose only predicate is identity, whose only nonlogical vocabulary is the abstraction operator, and whose axioms are all first-order instances of Frege's Axiom V is shown to be undecidable.     

Impact of length of unemployment and age on jobless men and women: a comparative analysis

The study examined differences in job search intensity, as well as attitudes toward unemployment and related responses among a sample of 559 jobless Israelis. Groups of participants were distinguished according to sex, age, and length of unemployment. The findings revealed that job search intensity, psychological stress, and work centrality were highest among participants who had been unemployed for 2 to 3 months, and gradually declined for longer periods of unemployment. Moreover, middle‐aged participants spent more hours per week searching for jobs and mentioned fewer advantages of unemployment than did the younger groups. Furthermore, women reported a sharper decline in health as a result of unemployment, as well as lower levels of work centrality.
