Coarse-to-fine encoding of spatial frequency information into visual short-term memory for faces but impartial decay

Face perception studies investigated how spatial frequencies (SF) are extracted from retinal display while forming a perceptual representation, or their selective use during task-imposed categorization. Here we focused on the order of encoding low-spatial frequencies (LSF) and high-spatial frequencies (HSF) from perceptual representations into visual short-term memory (VSTM). We also investigated whether different SF-ranges decay from VSTM at different rates during a study-test stimulus-onset asynchrony. An old/new VSTM paradigm was used in which two broadband faces formed the positive set and the probes preserved either low or high SF ranges. Exposure time of 500 ms was sufficient to encode both HSF and LSF in the perceptual representation (experiment 1). Nevertheless, when the positive-set was exposed for 500 ms, LSF-probes were better recognized in VSTM compared with HSF-probes; this effect vanished at 800-ms exposure time (experiment 2). Backward masking the positive set exposed for 800 ms re-established the LSF-probes advantage (experiment 3). The speed of decay up to 10 seconds was similar for LSF- and HSF-probes (experiment 4). These results indicate that LSF are extracted and consolidated into VSTM faster than HSF, supporting a coarse-to-fine order, while the decay from VSTM is not governed by SF.     

High arousal and low arousal work-related positive affects and basal cardiovascular activity

Basal cardiovascular activity may be modulated by positive affect activation levels. In the current study, it was hypothesized that work-related high arousal positive affect (HAPA) will have a U-shaped association with basal cardiovascular activity and low or un-aroused positive affect (LAPA) will be negatively associated with basal cardiovascular activity. Participants were 1807, apparently, healthy adults. HAPA and LAPA were assessed with the Job-related Affective Well-being Scale. Outcome measures were resting heart rate (HR), systolic (SBP), and diastolic blood pressure (DBP) levels. Results for HAPA supported the hypothesized relationships, such that HR and SBP were lower when HAPA was at moderate levels, but higher when HAPA was at high or low levels. LAPA was negatively associated with SBP and DBP. Our findings suggest that HAPA and LAPA have differential consequences regarding cardiovascular function.     

Seeing what you ought to see: The role of contextual factors in the social perception of achievement emotions

To assess the impact of context information on emotion perception, participants saw a picture of a male or female person with either a neutral, happy or sad facial expression and received information about the context in which the picture was taken. Their task was to rate the emotion actually expressed in the photo (i.e., focal emotions) as well as emotions not actually expressed (i.e., non-focal emotions) and inferences extracted from them. We predicted and found that context information affected both the perception of emotions and the inferences that the observers drew from them. Perceivers used context information in order to make sense of what was perceived to the extent that in the case of neutral expressions and for non-focal emotions, they “see” things that do not actually exist.     

The associations of the Five Factor Model of personality with inflammatory biomarkers: A four-year prospective study

This study evaluated the associations of the Five Factor Model of personality with two inflammation biomarkers, C-reactive protein and fibrinogen, and the possible moderating effects of common health-related behaviors (physical activity and smoking) concurrently and over four years, while adjusting for socio-demographic and health status. Participants were individuals who underwent a health examination at two points of time, T1 (n = 1709) and T2 (n = 923), about four years apart. Regression analyses uncovered positive associations between Neuroticism and Extraversion with two inflammatory biomarkers at baseline (T1) and over time (T2) and increases in their levels over time. Additionally, a synergistic interaction of neuroticism and physical inactivity was associated with higher levels of inflammation biomarkers at both time periods. Openness was negatively associated with inflammation biomarkers at T1 and T2, but not with changes in their levels. No significant associations were found for Agreeableness and Conscientiousness. The results suggest that personality traits might be involved in the inflammatory process both concurrently and over time, and thus indicate a possible mechanism by which personality traits might influence health, especially cardiovascular disease risk.     

Processing lexical ambiguity and visual word recognition in a deep orthography

We investigated the effect of semantic and phonemic ambiguity on lexical decision and naming performance in the deep Hebrew orthography. Experiment 1 revealed that lexical decisions for ambiguous consonant strings are faster than those for any of the high- or low-frequency voweled alternative meanings of the same strings. These results suggested that lexical decisions for phonemically and semantically ambiguous Hebrew consonant strings are based on the ambiguous orthographic information. However, a significant frequency effect for both ambiguous and unambiguous words suggested that if vowels are present, subjects do not ignore them completely while making lexical decisions. Experiment 2 revealed that naming low-frequency voweled alternatives of ambiguous strings took significantly longer than naming the high-frequency alternatives or the unvoweled strings without a significant difference between the latter two string types. Voweled and unvoweled unambiguous strings, however, were named equally fast. We propose that semantic and phonological disambiguation of unvoweled words in Hebrew is achieved in parallel to the lexical decision, but is not required by it. Naming Hebrew words usually requires a readout of phonemic information from the lexicon.     

Using a threat of divorce for maintaining family homeostasis within families in extreme distress (FED)

This paper describes a phenomenon of using a threat to divorce by families in extreme distress (FED) as a way of maintaining family homeostasis; that is, using a threat to divorce but never really implementing it. By relating to processes, such as social exchange and attachment, that often take place in the decision-making of divorce, we try to understand why those families choose to use the threat, thereby explaining this phenomenon. Using components of defining family boundaries, excitement and power struggle, we are thus able to better understand the existence of the phenomenon among FED.     

Simulating correlated multivariate nonnormal distributions: Extending the fleishman power method

A procedure for generating multivariate nonnormal distributions is proposed. Our procedure generates average values of intercorrelations much closer to population parameters than competing procedures for skewed and/or heavy tailed distributions and for small sample sizes. Also, it eliminates the necessity of conducting a factorization procedure on the population correlation matrix that underlies the random deviates, and it is simpler to code in a programming language (e.g., FORTRAN). Numerical examples demonstrating the procedures are given. Monte Carlo results indicate our procedure yields excellent agreement between population parameters and average values of intercorrelation, skew, and kurtosis.     

Aspects of fear of personal death,levels of awareness,and religious commitment

This study used a multidimensional and multilevel approach to study the relation between fear of death and religious commitment. A multidimensional self-report measure of fear of personal death, four TAT cards known to elicit a relatively high frequency of death themes, and an index of Jewish religious commitment were administered to 178 young male Jewish Israelis. Unidimensional and multidimensional analysis of these measures suggested that Jewish religious commitment is related to a heightened specific sensitivity to death at different levels of awareness.     

Long-Term successful Marriages in Israel

Long-Term Marriages (LTM) in Israel is part of a larger on-going international research. Our study focuses on two related questions: Are all long term marriages successful and satisfying? Similar studies have been undertaken in the United States, Sweden, Germany, and Chile. This paper focuses on the Israeli results with a few cross-cultural comparisons. Israel adds several unique features to the research: the people to whom LTM applies have emigrated to Israel from 112 different countries, with different cultures and nationalities; how Holocaust survivors are distributed in comparison to the rest of the population; Israel has the lowest divorce rate in the west; family life being a highly valued norm among Jewish people, it will be interesting to determine what keeps couples together and whether the motives and ingredients for satisfying marriages are similar or different from other countries.     

Participant modelling training programme: Tutoring the paraprofessional

A participant modelling training programme designed to improve self-efficacy and the ability to cope effectively with stressful situations was implemented with paraprofessional young counsellors who work in conjunction with youth advancement counsellors. Self-efficacy was measured by assessing their beliefs about their ability to cope effectively and successfully with various situations. Their motivation to engage in such a task was also assessed before and after the training programme. Contrary to prediction, following the training the self-efficacy of subjects decreased significantly. However, their motivation to get started and become involved with the disadvantaged youth significantly increased. The results are discussed in terms of reality perception and participant modelling training.
