Morphological analysis of disrupted morphemes: Evidence from Hebrew

In concatenative languages such as English, the morphemes of a word are linked linearly so that words formed from the same base morpheme also resemble each other along orthographic dimensions. In Hebrew, by contrast, the morphemes of a word can be but are not generally concatenated. Instead, a pattern of vowels is infixed between the consonants of the root morpheme. Consequently, the shared portion of morphologically-related words in Hebrew is not always an orthographic unit. In a series of three experiments using the repetition priming task with visually presented Hebrew materials, primes that were formed from the same base morpheme and were morphologically-related to a target facilitated target recognition. Moreover, morphologically-related prime and target pairs that contained a disruption to the shared orthographic pattern showed the same pattern of facilitation as did nondisrupted pairs. That is, there was no effect over successive prime and target presentations, of disrupting the sequence of letters that constitutes the base morpheme or root. In addition, facilitation was similar across derivational, inflectional and identical primes. The conclusion of the present study is that morphological effects in word recognition are distinct from the effects of shared structure.     

Hardiness and sense of coherence and their relation to negative affect

This study attempted to determine the degree to which measures of health proneness and measures of negative affect represent two distinct, although related, constructs. In addition, it examined the relation between Antonovsky's salutogenic construct of sense of coherence (SOC) and Kobasa's health proneness construct of hardiness. Five health proneness and three negative affect measures were filled out by 164 male patients with coronary heart disease. The pattern of correlations between these measures and confirmatory factor analysis indicated that although the measures of health proneness are negatively related to measures of negative affect, these two sets of measures and the constructs to which they are related can be differentiated from each other. However, SOC was found to be less independent of negative affect than was hardiness.     

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.
