The evolution of pure alexia: a longitudinal study of recovery

This case report documents the partial recovery, over a 12-month period, of pure alexia in an adult female following a left occipital infarction. Measures of speed and accuracy were obtained on an oral reading and a lexical decision task immediately postonset and then on 10 subsequent occasions. Explicit letter-by-letter reading was observed only during the first week poststroke but a significant effect of word length was seen in all testing sessions. Reading accuracy was relatively good at all stages and reading latency showed a remarkable decrease over time but did not reach normal reading rates. The inability to use higher-order orthographic knowledge, as manifest in the absence of a word superiority effect, was still noted at one year postonset. We therefore concluded that the change in behavior was attributable to increased proficiency in the use of the adaptive letter-by-letter procedure rather than to the resolution of the underlying deficit. It is suggested that longitudinal neurobehavioral studies add to our understanding of the alexic deficit and provide insight into the recovery process.     

The evolution of chronic back pain problems: a longitudinal study.

A longitudinal evaluation of the recovery from an acute back pain episode was undertaken on 117 sufferers, with assessments at the onset, 3 and 6 months. The number of individuals still reporting pain at 6 months, and therefore qualifying for 'chronic pain', was considerably higher than expected (40%). At 6 months, the persisting pain problems were found to be moderate to severe in intensity in approx. 20% of cases. Despite the pain, the chronic sufferers showed gradual continuing adjustments to it, re-establishing activities despite pain. Most of the change in the pain components (cognitive, subjective, behavioral, depression, anxiety) occur in the first 3 months, after which considerable stability is evident in the residual problem. In contrast, the impact of the pain and the consequent disability decline more markedly and continue to do so right up to the 6 month point. There was no evidence of chronic pain evolving and growing, but rather of a persistence of the acute presentation.     

Relation of emotion-related regulation to children's social competence: a longitudinal study

The differential relations of children's emotion-related regulation (i.e., effortful control and impulsivity) to their personality resiliency, adult-rated popularity, and social competence were examined in children who were 4.5-7.9 years old and who were remeasured 2 years later. Parents and teachers reported on all constructs, and children's attentional persistence was observed. Structural equation modeling was used to test the mediating role of resiliency on the relations between regulation/control and popularity using two-wave longitudinal data. The results provide some evidence of the mediating role of resiliency in the relations between effortful control and popularity, provide some evidence of bidirectional effects, and also buttress the view that emotional regulation should be differentiated into effortful and reactive forms of control.     

Stress-buffering effects of social support: A longitudinal study

The purpose of the present study was to investigate the effects of stress and social support in a longitudinal design. A sample of mature female students took part in a study that measured stress, social support, and psychiatric symptoms at two points 6 months apart. The results showed that the Time 1 measure of social support was a significant predictor of Time 2 symptoms when Time 1 symptoms were controlled for. Furthermore, a stress-buffering effect was obtained for Emotional support, but not for Practical support in conjunction with life events that occurred in the follow-up phase. Some of the conditions under which stress-buffering effects should be obtained are briefly considered.     

The role of social axioms in predicting life satisfaction: a longitudinal study in Hong Kong

Data from a 1-year, longitudinal study were utilized to explore the role of five pan-cultural beliefs about the world (social axioms) in predicting life satisfaction. It was hypothesized that higher levels of social cynicism would predict lower satisfaction with life because cynical persons set in motion a self-fulfilling prophecy of unrewarding social outcomes. The negative social feedback thus engendered results in lower levels of self-esteem, which mediates the effect of socially cynical beliefs on life satisfaction. These findings were confirmed in a longitudinal study of Chinese undergraduates in Hong Kong. Their implications were explored by considering the role of beliefs about␣the world upon additional mediators of life satisfaction in different cultural settings and for engaging in therapeutic interventions with distressed clients.     

Culture and social distance: a case study of methodological cautions

The authors presented, as a case study of methodological challenges in cross-cultural research, E. S. Bogardus's (1925) Social Distance Scale, which requires respondents to indicate the social distance between themselves and others. The meaningfulness of the scale depends on the assumption that respondents believe that the magnitude of social distance increases as one moves through the social categories of family member, friend, neighbor, coworker, and citizen. The authors tested this assumption for English Canadian, French Canadian, Jewish, Indian, Algerian, and Greek participants, all 1st-generation immigrants in Montreal. The participants rated their willingness to associate with members of each of the other ethnic groups in 5 social categories. The percentage of respondents in each sample whose data conformed to the prediction ranged from 63.7% to 98.0%, with English Canadian, French Canadian, and Jewish respondents providing responses most consistent with the predicted pattern. The Indian and Algerian respondents' data were the least consistent with the predicted pattern, especially when rating members of their own ethnic groups.     

The extended body: a case study in the neurophenomenology of social interaction

There is a growing realization in cognitive science that a theory of embodied intersubjectivity is needed to better account for social cognition. We highlight some challenges that must be addressed by attempts to interpret ‘simulation theory’ in terms of embodiment, and argue for an alternative approach that integrates phenomenology and dynamical systems theory in a mutually informing manner. Instead of ‘simulation’ we put forward the concept of the ‘extended body’, an enactive and phenomenological notion that emphasizes the socially mediated nature of embodiment. To illustrate the explanatory potential of this approach, we replicate an agent-based model of embodied social interaction. An analysis of the model demonstrates that the extended body can be explained in terms of mutual dynamical entanglement: inter-bodily resonance between individuals can give rise to self-sustaining interaction patterns that go beyond the behavioral capacities of isolated individuals by modulating their intra-bodily conditions of behavior generation.     

Diagnostic differences in social anhedonia: a longitudinal study of schizophrenia and major depressive disorder

This study examined the hypothesis that, in schizophrenia, elevated trait social anhedonia (SA) is a stable individual difference, whereas in depression, increased SA is a reflection of a current clinical state that will diminish with recovery. Differences in trait Negative Affect (NA) and Positive Affect (PA) were also examined. Individuals with schizophrenia (n = 55) and depression (n = 34) were evaluated at baseline during hospitalization and compared with nonpsychiatric control participants (n = 41). Participants were assessed again at a 1-year follow-up. At baseline, compared with control participants, individuals with schizophrenia and depression were both characterized by elevated SA, greater NA, and lower PA. In schizophrenic individuals, elevated SA remained stable over the follow-up. However, in recovered depressed patients, SA declined over the follow-up period. Group differences remained in NA and PA over the 1-year follow-up. These results support the view that elevated SA is enduring in schizophrenia but that elevated SA is transiently related to clinical status in depression.     

The influence of social and symbolic cues on observers' gaze behaviour

Research has shown that social and symbolic cues presented in isolation and at fixation have strong effects on observers, but it is unclear how cues compare when they are presented away from fixation and embedded in natural scenes. We here compare the effects of two types of social cue (gaze and pointing gestures) and one type of symbolic cue (arrow signs) on eye movements of observers under two viewing conditions (free viewing vs. a memory task). The results suggest that social cues are looked at more quickly, for longer and more frequently than the symbolic arrow cues. An analysis of saccades initiated from the cue suggests that the pointing cue leads to stronger cueing than the gaze and the arrow cue. While the task had only a weak influence on gaze orienting to the cues, stronger cue following was found for free viewing compared to the memory task.     

Emotion regulation and peer-rated social functioning: A 4-year longitudinal study

Different emotion regulation strategies have been linked to distinct social outcomes, but only concurrently or in the short-term. The present research employed a 4-year longitudinal design with peer-reported measures of social functioning to examine the long-term social effects of emotion regulation. Individual differences in suppression before entering college predicted weaker social connections (e.g., less close relationships) at the end of college, whereas reappraisal predicted stronger social connections and more favorable sociometric standing (e.g., higher social status). These effects of emotion regulation remained intact even when controlling for baseline social functioning and Big Five personality traits. These findings suggest that individual differences in the use of particular emotion regulation strategies have an enduring impact, shaping the individual’s social environment over time.     

On the autonomy of mental processes: a case study of arithmetic

We define a process as autonomous if it can begin without intention, and if it can run on to completion without intention. We develop empirical criteria for determining whether a process can begin without intention, for determining whether it begins in the same way without intention as it does with intention, and for determining whether it can run on to completion without intention once it begins. We apply these criteria to assess the autonomy of the processes underlying simple mental arithmetic--the addition and multiplication of single digits--and find evidence that simple arithmetic may be only partially autonomous: It can begin without intention, but does not begin in the same way without intention as with intention and does not run on to completion without intention. This conclusion suggests there may be a continuum of autonomy, ranging from completely autonomous to completely nonautonomous.     

The case of Dr. Jekyll and Mr. Hyde: a kinematic study on social intention

The aim of the present study was to investigate the effects of social intentions on action. Participants (N=13) were requested to reach towards, grasp an object, and either pass it to another person (social condition) or put it on a concave base (single-agent condition). Movements' kinematics was recorded using a three-dimensional motion analysis system. The results indicate that kinematics is sensitive to social intention. Movements performed for the 'social' condition were characterized by a kinematic pattern which differed from those obtained for the 'single-agent' condition. Results are discussed in terms of a motor simulation hypothesis, which assumes that the same mechanisms underlying motor intention are sensitive to social intentions.     

Studies in social influence: II. Instrumental and symbolic influence

In this article we have dealt with a critical analysis pertaining to the notion of the informational influence. We hereby show that in every inter-actionary situation, the judgments emitted by the source (influence agent) appear to contain informations on the judged objects from their elementary content and, at the same time, from their organisation, like indications on the source itself, on its purpose. In this manner, we have come to distinguish the instrumental influence from the symbolical influence. An experiment where the subjects have to judge the number of points appearing on the slides shows that this distinction reveals what happens in the process of influence.     

Development of infant crying behavior: A longitudinal case study

This study documents the development of infant crying behavior during the second half of the first year (across a key developmental transition). Two female infants were observed twice a month for 6 months when the infants were between 7 and 14 months of age. The infants exhibited crying behavior that seemed to become more sophisticated with increasing age. This marked a proactive stance in communicating with the mother on the part of the infant. Interestingly, at 11–12 months, “fake crying” was observed during a naturalistic interaction with the mother. This implied that deceptive infant behavior could be seen at quite an early stage.
