Motivational effects in the mere-exposure paradigm

Three experiments investigated the effects of time-pressure and evaluation apprehension on the mere-exposure phenomenon (Zajonc, 1968). Subjects viewed slides of abstract paintings at different frequencies of exposure and subsequently indicated their liking for the stimuli. Evaluation apprehension during the assessment phase consistently undermined mere-exposure effects. Furthermore, when evaluation apprehension was high, time-pressure magnified those effects. These findings were discussed in terms of the notions that (1) prior exposure may increase the sense of processing fluency associated with a stimulus (Jacoby & Kelley, 1990), (2) fluency may be interpreted as plausibility of a judgmental cue evoked by the stimulus, (3) motivational factors like time-pressure and evaluation apprehension may moderate the impact of plausibility information on judgment, hence, may moderate ‘mere-exposure’ effects.     

Devaluation versus enhancement of attractive alternatives: a critical test using the calibration paradigm

The calibration paradigm was used to test the competing hypotheses that (a) commitment motivates unduly negative evaluations of attractive alternatives (devaluation) versus (b) low commitment motivates exaggerated positive evaluations of attractive alternatives (enhancement). Single participants and dating participants low and high in relationship commitment were presented with an attractive, available person of the opposite sex and asked to judge the person's romantic appeal from their own perspective or from the perspective of their friends. Contrary to predictions based on the enhancement hypothesis, single and low-commitment participants did not provide higher ratings from their own perspective. In support of devaluation and calibration hypotheses, committed participants did provide lower ratings from their own perspective. Singles did not rate the target less attractive in a third condition in which the target was unavailable. However, dating participants, regardless of commitment level, rated the unavailable alternative negatively, consistent with social comparison processes and interdependence theory.     

HeartMath: a positive psychology paradigm for promoting psychophysiological and global coherence

This article proposes HeartMath as a positive psychology paradigm for promoting psychophysiological and global coherence . It provides evidence for the value of psychophysiological and global coherence, with special reference to human functioning through synchronisation between positive emotions, cardiovascular, respiratory, nervous, immune and other physiological systems . Various HeartMath tools and techniques are described and evidence for their effectiveness provided, drawing from several related South African studies . Psychophysiological and global coherence bear promise as fertile fields for future research and intervention of great potential to develop humanity and promote global health and wellbeing.     

The reverse affect test: a new interference task

A new interference test requires subjects to read a list of 10 pairs of words with affective responses inappropriate to the terms listed. 80 adults were given the task with significant interference occurring which decreased speed and accuracy of performance. Significantly increased variability was also noted under the condition of interference. The source of interference is discussed and possible uses of this new task are described.     

Deep dyslexia and semantic errors: a test of the failure of inhibition hypothesis using a semantic blocking paradigm

Deep dyslexia is an acquired reading disorder that involves the production of semantic errors and the inability to read aloud nonwords successfully. Several explanations for this reading impairment posit multiple loci of damage to account for the various error types produced in deep dyslexia. In contrast, the failure of inhibition hypothesis suggests that damage in the phonological output lexicon alone can explain these errors. Specifically, this hypothesis proposes normal processing via orthographic and phonological reading routes, as well as an intact semantic system. However, slowed or reduced inhibitory connections result in the failure to suppress spuriously activated neighbours in the phonological output lexicon, where neighbourhood can be defined in terms of phonology, orthography, or semantics. Given a failure to inhibit semantically related candidates, semantic reading errors occur. Important to the test of this hypothesis is that it evolves several predictions that are contrary to performance observed in the normal population. In particular, semantic errors are predicted to be greater in conditions where words are blocked according to semantic category than in random presentations. In addition, a semantic interference effect is expected. The results of semantic blocking were consistent with these predictions and lend support to the failure of inhibition hypothesis.     

No aging bias favoring memory for positive material: evidence from a heterogeneity-homogeneity list paradigm using emotionally toned words

Some authors argue for a memory advantage of older adults for positively toned material. To investigate the contribution of selective processing to a positivity effect, the authors investigated young (n = 72, aged 18 to 31) and older (n = 72, aged 64 to 75) adults' memory for emotionally toned words using a multitrial paradigm that compares performance for heterogeneous (mixed valence) and homogeneous (single valence) lists. Regarding the age comparison, there was no evidence for an aging bias favoring positive material. Moreover, older adults' memory was less affected by emotion-based processing prioritization. Although there was no support for age-specific processing biases in memory for emotionally toned words, the findings are consistent with proposals that negative information receives processing priority in some contexts. Possible limits to the generalizability of the present findings (e.g., to nonverbal material) are discussed.     

Individual differences in motives for regulating affect intensity: positive trait affect and the value of trait-consistent affect

We examined individual differences in the motivation to regulate affect intensity. In three samples (total n?=?1082) we used structural equation modeling and found support for a serial mediation model in which positive trait affect predicted the motivation to increase the intensity of positive affect and decrease the intensity of negative affect, indirectly, through the commonality and value of positive affect. These findings indicate that trait affect drives regulation motives for multiple parameters of affect: people most value, and are motivated to feel, moods and emotions that match their typical experiences on intensity as well as valence.

     

Savoring versus dampening: self-esteem differences in regulating positive affect

Five studies examined the hypotheses that when people experience positive affect, those low in self-esteem are especially likely to dampen that affect, whereas those high in self-esteem are especially likely to savor it. Undergraduate participants' memories for a positive event (Study 1) and their reported reactions to a success (Study 2) supported the dampening prediction. Results also suggest that dampening was associated with worse mood the day after a success (Study 2), that positive and negative affect regulation are distinct, that self-esteem is associated with affect regulation even when Neuroticism and Extraversion are controlled (Studies 3 and 4), and that self-esteem may be especially important for certain types of positive events and positive affect regulation (Study 5).     

Personality and the four faces of positive affect: A multitrait-multimethod analysis using self- and peer-report

The present study investigates the relationship between personality and positive affects (contentment, love, interest, and joy). Using multitrait-multimethod analysis and structural equation modeling procedures with self- and peer-report, the authors demonstrated the importance of differentiating between the positive affects. A multidimensional model fitted better than a general-factor model. Concerning the personality–affect relationship, the strongest relations were found between extraversion and both joy and love, agreeableness and love, openness to experiences and interest, and neuroticism and contentment. Thus, results suggest that it is insufficient to concentrate solely on extraversion when investigating the personality–positive affect relationship.     

Psychopathy in Iran: a cross-cultural study

Few cross-cultural studies have assessed psychopathy and none have included a sample from non-western countries. This study investigated the factor structure of the Psychopathy Checklist: Screening Version (PCL:SV) in an Iranian sample, and compared the results with a western sample. Three hundred fifty-one Iranian prisoners were compared with 405 participants of the standardization sample of the PCL:SV. Confirmatory factor analysis and item response theory method were used for data analysis. The Iranian data fitted well with the hierarchical three-factor model of psychopathy and neither two- nor four-factor models showed an adequate fit. Differential item functioning existed across samples, with discriminatory power of factor 1 (arrogant and deceitful interpersonal style) being lower in the Iranian sample that for factor 2 (deficient emotional experience) being greater in the Iranian sample than the standardization sample. Deficient emotional experience might be the most significant factor in diagnosing psychopathy, regardless of the studied culture. Other factors appear to be relatively culture-specific.     

Changes in positive and negative affect as predictors of change in felt age: Results from the Health and Retirement Study

The present study aimed to examine how changes in positive and negative affect and their interaction predict changes in felt age in a longitudinal design of two waves drawn from the Health and Retirement Study (HRS). Participants (n = 4174) at an average age of 67.97 completed the 2008 and 2012 left behind questionnaire of the HRS. Our results showed that an increase in positive affect and a decrease in negative affect from Wave 1 to Wave 2 predicted an accelerated decrease in felt age. There was an interaction effect showing that for those with an increase in negative affect, a higher change in positive affect predicted reduced odds for accelerated increase in felt age. To conclude, improving favorable change in the combination between positive and negative affect might in turn relate to the individual’s self-perceptions of aging, in the second half of life.     

Affect sensitivity and affect regulation in dealing with positive and negative affect

Interactions between two types of affect sensitivity and two types of affect regulation were tested: low sensitivity to positive affect and high sensitivity to negative affect were expected to become maladaptive when self-motivation and self-relaxation are low, respectively. Consistent with expectations, specific Sensitivity × Regulation interactions emerged: low sensitivity to positive affect (i.e., independent, schizoid-like personality) was only associated with reduced emotional well-being when self-motivation was low. High sensitivity to negative affect (i.e., self-critical, avoidant-like personality) was only associated with psychosomatic symptoms when self-relaxation was low. In a subsample, the same results were obtained longitudinally. Findings support the distinction between affect sensitivity and affect regulation. Furthermore, affect regulation can be differentiated into self-motivation and self-relaxation.     

Interpretive biases in chronic insomnia: an investigation using a priming paradigm

Disorder-congruent interpretations of ambiguous stimuli characterize several psychological disorders and have been implicated in their maintenance. Models of insomnia have highlighted the importance of cognitive processes, but the possibility that biased interpretations are important has been minimally investigated. Hence, a priming methodology was employed to investigate the presence of an interpretive bias in insomnia. A sample of 78 participants, differing in the presence of a diagnosis of insomnia, severity of sleep disturbance, and sleepiness, was required to read ambiguous sentences and make a lexical decision about target words that followed. Sleepiness at the time of the experiment was associated with the likelihood with which participants made insomnia and threat consistent interpretations of ambiguous sentences. The results suggest that there is a general bias towards threatening interpretations when individuals are sleepy and suggests that cognitive accounts of insomnia require revision to include a role for interpretative bias when people are sleepy. Future research is required to investigate whether this interpretive bias plays a causal role in the maintenance of insomnia.     

Happy as a lark: morning-type younger and older adults are higher in positive affect

A literature on young adults reports that morning-type individuals, or "larks," report higher levels of positive affect compared with evening-type individuals, or "owls" (Clark, Watson, & Leeka, 1989; Hasler et al., 2010). Morning types are relatively rare among young adults but frequent among older adults (May & Hasher, 1998; Mecacci et al., 1986), and here we report on the association between chronotype and affect in a large sample of healthy younger and older adults. Overall, older adults reported higher levels of positive affect than younger adults, with both younger and older morning types reporting higher levels of positive affect and subjective health than age mates who scored lower on morningness. Morningness partially mediated the association between age and positive affect, suggesting that greater morningness tendencies among older adults may contribute to their improved well-being relative to younger adults.     

Working memory load can both improve and impair selective attention: Evidence from the Navon paradigm

Selective attention to relevant targets has been shown to depend on the availability of working memory (WM). Under conditions of high WM load, processing of irrelevant distractors is enhanced. Here we showed that this detrimental effect of WM load on selective attention efficiency is reversed when the task requires global- rather than local-level processing. Participants were asked to attend to either the local or the global level of a hierarchical Navon stimulus while keeping either a low or a high load in WM. In line with previous findings, during attention to the local level, distractors at the global level produced more interference under high than under low WM load. By contrast, loading WM had the opposite effect of improving selective attention during attention to the global level. The findings demonstrate that the impact of WM load on selective attention is not invariant, but rather is dependent on the level of the to-be-attended information.
