Semantic and affective manifestations of ambi (valence)

ABSTRACT

People sometimes report both pleasant and unpleasant feelings when presented with affective stimuli. However, what is reported as “mixed emotions” might reflect semantic knowledge about the stimulus (Russell, J. A. (2017). Mixed emotions viewed from the psychological constructionist perspective. Emotion Review, 9(2), 111–117). The following research examines to what degree self-reported mixed emotions represent actual feelings compared to knowledge about the stimulus. In a series of three experiments, participants reported either their feelings or their knowledge in response to affective stimuli. In Experiment 1, we sampled the entire IAPS pictorial space and examined the proportion of mixed emotion ratings using feelings-focused and knowledge-focused self-reports. We found a higher degree of mixed emotions under knowledge-focused than feelings-focused self-reports. In Experiment 2, we used a priori selected pictures to elicit mixed emotions. The proportion of mixed emotions was again higher under knowledge-focused instructions. In Experiment 3, we used movie clips that were previously used to elicit mixed emotions. In contrast to Experiments 1 and 2, there was no difference between feelings-focused and knowledge-focused self-reports. The results suggest a strong semantic component and a weak experiential component of self-reports in the case of pictorial stimuli. However, ambivalent movie clips elicited a stronger experiential component, thus supporting the existence of mixed emotions at the level of feelings.     

Individual and Community Resilience Factors Among Lesbian,Gay, Bisexual,Queer and Questioning Youth and Adults in Israel

Drawing on resilience theories, this study examined the individual and community factors of Israeli lesbians, gays, bisexuals, queers, and questioning (LGBQs) that contribute to positive mental health and the degree to which individual and community protective factors mitigate the adverse effect of risk factors for poor mental health. Differences in resilience factors between LGBQ youth and adults were explored. Data were collected on 890 LGBQ youth and adults. Findings emphasize the role of community‐level resilience factors in the lives of LGBQs, and that these support systems differ slightly between the two age groups. Among youth, family support was both a strong predictor for well‐being and a protective factor for mental distress. Although family support was found as a resilience factor among adults as well, other community‐level factors (friends’ support, LGBT connectedness and having steady partner) were found as protective factors for poorer mental health. These findings suggest for efforts on fostering familial support for LGBQ youth and a multi‐level system that offers support at the familial, peer, relationship and community levels for both LGBQ youth and adults.     

The timing deficit hypothesis of dyslexia and its implications for Hebrew reading

Vast amounts of neuropsychological evidence have been collected in recent years in support of the hypothesis that developmental dyslexia is caused not only by phonological deficits, but also by timing deficits that affect all senses (e.g., Tallal, Miller, & Fitch, 1995; Stein & Walsh, 1997). In parallel, recent developments in the study of Hebrew reading place heavy emphasis on root awareness in the mental lexicon and early root extraction in the process of word identification (e.g., Frost, Forster, & Deutch, 1997). The present study creates a link between the timing hypothesis and the special demands of Hebrew reading. The performance of dyslexics and normally reading children is compared on tasks requiring visual extraction of trigrams that approximates extracting roots out of Hebrew words. Partial findings show that dyslexics take longer and make more errors while performing trigram extractions on all levels examined, and that sequentiality in the task affects dyslexics and skilled readers in different ways.     

Linguistic and nonlinguistic auditory processing of rapid vowel formant (F2) modulations in university students with and without developmental dyslexia

To help resolve the issue of whether developmental dyslexia (DD) is related to central auditory processing deficits or to language-specific processing deficits, we had nine dyslectic and nine nondyslectic right-handed undergraduate students perform linguistic (Experiment 1: phoneme identification) and nonlinguistic (Experiment 2: formant rate change detection) tasks. In Experiment 1, subjects listened to synthetic vowels whose second formant (F2) was modulated sinusoidally with F1, F3, and F4 held constant. F2 modulation rate (4-18 Hz) was manipulated within and across stimuli. The groups did not differ in phoneme identification. Experiment 2 was run three times and showed that the control subjects' performance improved across runs whereas the dyslexics' deteriorated across runs (p < .0001), suggesting practice and fatigue effects, respectively. Performance on the two experiments correlated significantly and negatively for the dyslexic subjects only. These results suggest that resource depletion or frontal lobe dysfunction may be implicated in developmental dyslexia.     

Depression and social anxiety mediate the relationship between parenting styles and risk of eating disorders: A study among Arab adolescents

In multicultural Israel, the prevalence of eating disorders (EDs), a common chronic disorder among Western adolescents (especially females), has risen for Arab adolescents, who belong to an Eastern collectivist society. The study examines family and psychological factors that may increase the risk of EDs among Muslim Arab adolescents. We expected social anxiety and depressive symptoms to mediate the association between parenting styles and risk of EDs, with possible gender differences in the mediation model. Participants were 613 Muslim adolescents (394 females and 219 males); mean age = 15.4 ± 1.6; range = 12–19. The analyses revealed that the severity of depressive symptoms and especially social anxiety mediate the relationship between authoritarian parenting style and risk of EDs. Females reported higher levels of risk of EDs, social anxiety, depression and authoritative parenting style than males; no differences appeared for authoritarian or permissive parenting styles. The research sheds new light on risk factors for EDs and the likelihood of authoritarian parenting style and social anxiety being involved in the aetiology of EDs among Arab adolescents. The outcomes meaningfully add to understanding of specific psychological processes that may be associated with the risk of EDs in this population.     

Metalinguistic Awareness and Reading Performance: A Cross Language Comparison

The study examined two questions: (1) do the greater phonological awareness skills of billinguals affect reading performance; (2) to what extent do the orthographic characteristics of a language influence reading performance and how does this interact with the effects of phonological awareness. We estimated phonological metalinguistic abilities and reading measures in three groups of first graders: monolingual Hebrew speakers, bilingual Russian–Hebrew speakers, and Arabic-speaking children. We found that language experience affects phonological awareness, as both Russian–Hebrew bilinguals and the Arabic speakers achieved higher scores on metalinguistic tests than Hebrew speakers. Orthography affected reading measures and their correlation with phonological abilitites. Children reading Hebrew showed better text reading ability and significant correlations between phonological awareness and reading scores. Children reading Arabic showed a slight advantage in single word and nonword reading over the two Hebrew reading groups, and very weak relationships between phonological abilities and reading performance. We conclude that native Arabic speakers have more difficulty in processing Arabic orthography than Hebrew monolinguals and bilinguals have in processing Hebrew orthography, and suggest that this is due to the additional visual complexity of Arabic orthography.
