Discrimination of Facial Identity and Facial Affect by Temporal and Frontal Lobectomy Patients

The purpose of this study was to determine the extent to which lobectomy affects ability to discriminate facial identity or facial expression. Fifteen right temporal, 15 left temporal, 5 right frontal, and 4 left frontal lobectomy patients, pair-matched for age, sex, and education to normal control subjects, participated in this study. Tasks included a Facial Identity Matching Task and a Facial Affect Matching task. The lobectomized patients as a whole were significantly impaired on both tasks (22% decrement in performance). The patients made twice as many errors resulting from perseveration of response-set of the first condition (identity or emotion matching) into the second condition. The site of lobectomy did not influence general performance on any one task or selective performance on any subset of affective categories. It was concluded that all four brain regions play a significant and equal role in face processing, and that circuits more specifically dedicated to visual face processing, which are responsible for hemispheric dominance affects and affect/identity dissociations, are probably located more posteriorly in the brain. Finally, it was concluded that perseveration of acquired habit may, under specific conditions, characterize temporal lobe dysfunction just as much as frontal lobe dysfunction.     

Verbal Fluency,Semantics, Context and Symptom Complexes in Schizophrenia

Lexical-semantic access and retrieval was examined in 15 adults diagnosed with schizophrenia and matched controls. This study extends the literature through the inclusion of multiple examinations of lexical-semantic production within the same patient group and through correlating performance on these tasks with various positive and negative clinical symptoms. On tasks of verbal fluency, meaning generation, sentence production using contextual information and confrontation naming, participants with schizophrenia made significantly more semantic errors on naming tasks; produced fewer meanings for homophones; produced fewer items on semantic, phonological, cued and switching fluency tasks; and produced more errors on sentence production tasks when compared to healthy controls. Significant correlations were also observed between ratings of psychomotor poverty and measures of semantic production and mental inflexibility. This study has provided additional evidence for deficits in lexical-semantic retrieval which are not due to underlying semantic store degradation, do not involve phonological based retrieval, and at the level of sentence generation appear to vary as a function of the contextual constraints provided.     

The Political Context for Personal Empowerment: Continuing the Conversation

In our joint theoretical piece (Lamb and Peterson 2011), we attempted to find points of agreement and further elucidate points of disagreement in relation to the challenging issue of adolescent girls’ sexual empowerment. In particular, we evaluated the divisive question of whether girls’ subjective feelings of sexual empowerment qualify as some useful version of empowerment. We are grateful to the commentators for joining us in this productive and collaborative conversation. In this response, we summarize some of the themes raised by the commentators, and we look for points of agreement around which we, as feminists, can continue to build a conversation on this polarizing issue. We also attempt to better explore the possible relationship between subjective empowerment and political empowerment by resurrecting the idea that “the personal is political.”     

语境信息对面部表情加工的影响

为检验语境信息在面部表情加工和识别中的作用,通过两个实验考察语境信息的情绪性和自我相关性对中性以及不同强度恐惧面孔情绪加工的影响。结果发现,积极语境下中性情绪面孔效价的评分更高,自我相关语境下中性面孔唤醒度的评分更高;消极语境下面孔的恐惧情绪更容易被察觉。因此,面部表情加工中的语境效应表现为对中性情绪面孔的情绪诱发和增强作用,以及在情绪一致情况下对不同情绪强度面孔判断的促进作用。     

Gender Differences in Mother-toddler and Father-toddler Verbal Initiations and Responses during a Caregiving and Play Context

Contextual variations in mother-child and father-child verbal communication were examined among 80 U.S. families from Kansas who were predominately Caucasian (85%) and middle-class. There were 41 girls and 39 boys between 15- and 18-months-old observed with their mothers and fathers in separate play and caregiving laboratory situations. Parent and child behaviors were coded for verbal initiation and response strategies. MANOVA’s revealed more differences between mother’s and father’s verbal communication strategies in the play context than the caregiving context. Boy’s and girl’s verbal communication was relatively similar across contexts. The interactions between gender and context are discussed in relation to gender role development in the family.     

Traces of Terror: Subliminal Death Primes and Facial Electromyographic Indices of Affect

Previous research has found that both explicit and implicit reminders of one's mortality provoke hostile reactions to those who threaten one's worldview, but do not create conscious negative affect or electrodermal arousal. This study was conducted to investigate subtle affective reactions to subliminal death primes as indexed by measures of facial electromyography (EMG). Fifty-four participants were exposed to masked presentations of either the word dead or pain, and then to a worldview threatening essay. Facial EMG was recorded throughout. Analyses found the expected increase in worldview defense following mortality primes. Analyses also uncovered a novel finding with greater corrugator EMG specifically during exposure to the subliminal death but not subliminal pain primes, pointing to the sensitivity of facial EMG to unconscious cognition. However, there was little evidence for a mediating role of affect on worldview defense following exposure to death primes. Implications for understanding terror management processes and the effects of unconscious cognition on emotion are briefly discussed.     

Popularity in Environmental Context: Facial Feature Assessment of American Movie Actresses

The relationship between facial features of popular American movie actresses and the social and economic conditions of the United States from 1932 to 1995 was investigated. Facial photographs of popular American movie actresses were located and digitally converted to graphics files to allow measurement of facial features. When social and economic conditions in the United States were stagnant and pessimistic, American movie actresses with mature facial features (small eye size, thin cheeks, and large chins) were popular: When social and economic conditions were prosperous and optimistic, actresses with neonate facial features (large eye size, round cheeks, and small chins) were popular: Results support the hypothesis that popularity and facial feature preference is related to and changes based on environmental security.     

Social Effects of Facial Blushing: Influence of Context and Actor Versus Observer Perspective

Blushing is restricted to the facial area that is uncovered and in the center of social attention. Together with the observation that blushing typically occurs in interpersonal situations, it has been proposed that the blush might have acquired signaling properties with relevant social implications. Following such a functional perspective, this article evaluates the signal value and social effects of the blush. First, it is argued that the blush fulfils all criteria for being a reliable social signal. It seems impossible to fake or to suppress, and it seems to co‐occur with a specific mental state: The acute awareness that one’s goal of esteem before others is at stake. Second, it is illustrated that the social effects of the blush may greatly vary as a function of context. In contexts that clearly imply some kind of misbehavior, the blush has face‐saving properties. Yet, in many other contexts, such as merely being the center of attention or situations that are ambiguous with regard to the blushing actors’ antecedent behaviors, the blush may have undesirable effects. Third, it is illustrated that the signal value of the blush not only affects the observers but also the blushing actors. It is shown that the anticipated influence of one’s blushing on other people’s judgments may help explain why actors often consider blushing as a highly undesirable response, and why some people may even develop a phobic fear of blushing.     

How Does the Linguistic Distance Between Spoken and Standard Language in Arabic Affect Recall and Recognition Performances During Verbal Memory Examination

The current research examined how Arabic diglossia affects verbal learning memory. Thirty native Arab college students were tested using auditory verbal memory test that was adapted according to the Rey Auditory Verbal Learning Test and developed in three versions: Pure spoken language version (SL), pure standard language version (SA), and phonologically similar version (PS). The result showed that for immediate free-recall, the performances were better for the SL and the PS conditions compared to the SA one. However, for the parts of delayed recall and recognition, the results did not reveal any significant consistent effect of diglossia. Accordingly, it was suggested that diglossia has a significant effect on the storage and short term memory functions but not on long term memory functions. The results were discussed in light of different approaches in the field of bilingual memory.     

Cooperativity and Selectivity in Conversation

Conversing with others is a mundane, daily activity of nearly all humans, yet it is an extraordinary feat of social collaboration that depends on cooperation, social learning, and collective coordination across an array of caring relationships. This article briefly considers the cooperative and selective nature of language and something of its contributions to the structural, social, and developmental character of human action and cognition. In doing so, it introduces 3 other articles that form a special section of this issue that is a continuation of an earlier special issue (Fowler & Hodges, 2015). The evidence reviewed here points to the possibility that the integrated, synergistic, cooperative character of language may prove to be a particular strength of ecological approaches to cognition and action rather than a liability.     

Conversation and conditionals

I outline and motivate a way of implementing a closest world theory of indicatives, appealing to Stalnaker’s framework of open conversational possibilities. Stalnakerian conversational dynamics helps us resolve two outstanding puzzles for a such a theory of indicative conditionals. The first puzzle—concerning so-called ‘reverse Sobel sequences’—can be resolved by conversation dynamics in a theory-neutral way: the explanation works as much for Lewisian counterfactuals as for the account of indicatives developed here. Resolving the second puzzle, by contrast, relies on the interplay between the particular theory of indicative conditionals developed here and Stalnakerian dynamics. The upshot is an attractive resolution of the so-called “Gibbard phenomenon” for indicative conditionals.     

Party Pooper or Life of the Party: Dampening and Enhancing of Positive Affect in a Peer Context

Dampening and enhancing responses to positive affect have been linked to depressive symptoms. The main aim of the present study was to examine such responses in an interpersonal peer context and to examine their relation with depressive symptoms. A community sample of 665 seventh-graders (52.0% girls, Mage = 12.7 years) took part in the study. Using a newly developed questionnaire, the Co-Dampening and Co-Enhancing Questionnaire (CoDEQ), a two-factor model distinguishing co-dampening and co-enhancing was validated. Relations with general depressive symptoms, anhedonic symptoms, and friendship quality were investigated. The direction of relations was examined over a 1-year interval using cross-lagged analyses. Cross-sectional results revealed that higher levels of co-dampening and lower levels of co-enhancing were associated with more depressive and anhedonic symptoms, while controlling for co-rumination levels. For anhedonic symptoms, this pattern also held over and above intrapersonal dampening and enhancing. Friendship quality was related to higher concurrent levels of co-enhancing and lower levels of co-dampening. The longitudinal results pointed towards a scar model, in that both depressive and anhedonic symptoms predicted relative increases in co-dampening over time; however, this did not hold in a model in which dampening and enhancing were included as control variables.     

Verbal, Facial and Autonomic Responses to Empathy-Eliciting Film Clips by Disruptive Male Adolescents with High Versus Low Callous-Unemotional Traits

This study examined empathy-related responding in male adolescents with disruptive behavior disorder (DBD), high or low on callous-unemotional (CU) traits. Facial electromyographic (EMG) and heart rate (HR) responses were monitored during exposure to empathy-inducing film clips portraying sadness, anger or happiness. Self-reports were assessed afterward. In agreement with expectations, DBD adolescents with high CU traits showed significantly lower levels of empathic sadness than healthy controls across all response systems. Between DBD subgroups significant differences emerged at the level of autonomic (not verbal or facial) reactions to sadness, with high CU respondents showing less HR change from baseline than low CU respondents. The study also examined basal patterns of autonomic function. Resting HR was not different between groups, but resting respiratory sinus arrhythmia (RSA) was significantly lower in DBD adolescents with high CU traits compared to controls. Results support the notion that CU traits designate a distinct subgroup of DBD individuals.     

Age Differences in Perceived Positive Affect, Negative Affect, and Affect Balance in Middle and Old Age

Meta-analysis was used to synthesize findings from 125 studies on age differences in positive affect, negative affect, and affect balance. We found a small age-associated decline of positive affect and affect balance, and a small age-associated increase of negative affect. In addition, a quadratic age trend emerged, showing stronger declines of positive affect and stronger increases of negative affect in older subjects. Looking at changes of specific emotions, we found an age-associated decline of those positive and negative feelings that are associated with high arousal (e.g., feeling excited or upset), and an age-associated increase of positive and negative low-arousal emotions (e.g., feeling relaxed or depressed). Furthermore, older adults from the former communist Eastern European countries showed the strongest age-associated decline of positive affect and the strongest age-associated increase of negative affect. We conclude that age-associated losses in the oldest old and economic hardship make the optimization of subjective well-being increasingly difficult.     

Lateralized Changes in Regional Cerebral Blood Flow during Performance of Verbal and Facial Recognition Tasks: Correlations with Performance and “Effort”

Functional neuroimaging has been used to investigate neural substrates of mnemonic processes, and cerebral blood flow (CBF) measures have been sensitive to activation with memory tasks. Studies of memory with two-dimensional¹³³Xenon clearance techniques found that word and face recognition tasks produced contralateral CBF changes in mid-temporal cortical regions. This study replicated the activation paradigm, expanding to the three-dimensional resolution of positron emission tomography (PET). Word and face recognition, and a control baseline task were administered to 19 healthy right-handed volunteers (11 men, 8 women) during successive 10 min PET¹⁵O-water measures of CBF. Quantitative CBF rates were calculated with the arterial input function and the equilibrium model. Redistributions of blood flow were compared across tasks using both absolute and relative (region/whole brain) CBF.Replicating the¹³³Xenon clearance findings, CBF was “appropriately” lateralized during task performance (left–right for words > left–right for faces) in the mid-temporal region. Contrary to predictions, the recognition tasks did not activate expected mesolimbic or prefrontal areas. The task-induced CBF changes also correlated with performance. Bilateral CBF in mid-temporal and parahippocampal gyrus regions of interest correlated with the ability to correctly identify word targets (sensitivity). Left-lateralized CBF in the amygdala and hippocampus correlated with better word sensitivity as well as specificity (ability to correctly reject foils). Complementally, right-lateralized CBF in the parahippocampal gyrus correlated with better face specificity performance. In addition, left-lateralized CBF in the amygdala and right-lateralized CBF in the parahippocampal gyrus and hippocampus correlated with “mental effort” indices (task performance relative to basal ability) for word and face memory tasks, respectively. Thus, whereas this recognition task showed the expected lateralized increase in the mid-temporal region and not in frontal and limbic areas, lateralized activation in some of these areas was associated with better performance. Exploratory analyses on other regions showed lateralized changes in one additional temporal region, the occipital-temporal, and several limbic regions.
