What can a moving face tell us?

This research assessed the impact of facial motion on perceptions of age-related person qualities. Ss judged the power of point-light displays of the faces of children, middle-aged adults, and elderly adults. Ratings were obtained of (a) dynamic displays filmed while the stimulus persons were reciting the alphabet, (b) dynamic displays filmed, while the stimulus persons engaged in an interaction, and (c) static versions of the displays. Facial age exerted no effect on the perceived power of nondynamic displays. However, moving displays of children's faces were judged to be less powerful than were those of adults. Differences in perceived age could not explain these effects. The implications of these data for the developing area of social event perception are discussed.     

FOXP2 in focus: what can genes tell us about speech and language?

The human capacity for acquiring speech and language must derive, at least in part, from the genome. In 2001, a study described the first case of a gene, FOXP2, which is thought to be implicated in our ability to acquire spoken language. In the present article, we discuss how this gene was discovered, what it might do, how it relates to other genes, and what it could tell us about the nature of speech and language development. We explain how FOXP2 could, without being specific to the brain or to our own species, still provide an invaluable entry-point into understanding the genetic cascades and neural pathways that contribute to our capacity for speech and language.     

Biological specializations for speech: what can the animals tell us?

Language research over the past 40 years converges on the speech-is-special hypothesis (SiS), according to which speech perception and production are uniquely human adaptations. SiS is grounded in a variety of biological, developmental, and behavioral evidence. In some comparative studies, speechlike stimuli have seemed to cause nonhuman animals to exhibit humanlike performance functions. Auditorists—who believe that spoken language processing is executed by, and is explicable in terms of, general auditory mechanisms—have seized upon such studies as evidence that SiS is incorrect. However, it is difficult to identify biological and functional similarities across different species on the basis of behavior alone, and the elaborate training regimen that nonhuman animals require to achieve human performance levels undermines the significance of certain comparative studies. Both comparative and human behavioral research, including brain-imaging studies of functional localization, electrophysiological recordings of the neural basis of the perception-production link, and developmental studies of a time-locked schedule of language learning, favor SiS over auditorism.     

What can autism and dyslexia tell us about intelligence?

This paper argues that understanding developmental disorders requires developing theories and models that explicitly represent the role of general intelligence in the cognitive phenotype of the disorder. In the case of autism it is argued that the low-IQ scores of people with autism are not likely to be due to a deficit in the cognitive process that is arguably the major cause of mental retardation - namely, speed of processing - but rather low IQ reflects the pervasive and cascading effects of the deficit in the information-processing module that causes autism. In the case of dyslexia, two radically different models of reading disorder (ability = disability and a modular deficit model) are likely to be influenced by the effect of general intelligence on reading performance in ways that will remain unclear without an explicit model of how general intelligence influences reading.     

Saccadic eye movements: what do they tell us about aging cognition?

Although the relationship between age-related cognitive decline and saccadic eye movement (SEM) deficits has been outlined, specific cognitive alterations underlying age-related changes in saccadic performance remain unclear. This study attempted to better understand the nature of aging effects on SEMs. We compared SEMs in younger and older adults in prosaccade (PS) and antisaccade (AS) tasks under gap, step, and overlap conditions. We also examined relationships between these performances and several neuropsychological scores. Twenty-eight younger adults (YA), 24 older adults under 65 years (OA_<65) and 24 over 65 years (OA_>65) of age completed a neuropsychological evaluation, PS and AS tasks. Our results showed that latencies, AS cost, time to correct AS errors, and uncorrected AS, increased with aging. YA showed higher overlap effects than OA_>65 and OA_<65. Importantly, correlations and regressions revealed close relationships not only between latencies and processing speed measures but also between the AS cost and the inhibition process measures. Correct saccades and the time to correct AS errors were closely related to the inhibition process and cognitive flexibility measures. These findings suggest that the progressive age-related decline of processing speed and executive attention are associated with, and can be highlighted though SEMs in PS and AS tasks.     

Individual differences in mental rotation: what does gesture tell us?

Gestures are common when people convey spatial information, for example, when they give directions or describe motion in space. Here, we examine the gestures speakers produce when they explain how they solved mental rotation problems (Shepard and Meltzer in Science 171:701–703, 1971). We asked whether speakers gesture differently while describing their problems as a function of their spatial abilities. We found that low-spatial individuals (as assessed by a standard paper-and-pencil measure) gestured more to explain their solutions than high-spatial individuals. While this finding may seem surprising, finer-grained analyses showed that low-spatial participants used gestures more often than high-spatial participants to convey “static only” information but less often than high-spatial participants to convey dynamic information. Furthermore, the groups differed in the types of gestures used to convey static information: high-spatial individuals were more likely than low-spatial individuals to use gestures that captured the internal structure of the block forms. Our gesture findings thus suggest that encoding block structure may be as important as rotating the blocks in mental spatial transformation.     

What can performance tell us about learning? Explicating a troubled concept

The notion of “performance7rdquo; has a central place in the contemporary discourse of learning and competence. The notion is used to translate abstract ideas and ideals of lifelong learning, organizational learning, learning society, etc., into practical measures. Changes in performance provide the identifiable measures that learning has taken place, evidence of enhanced competency/capability. Different versions of the learning and competency/capability agenda may place different emphases upon the extent to which such performance changes may be predetermined or are essentially emergent, but the assumption remains that performance provides the basis for attribution that learning has (or has not) taken place. This article takes issue with the conventional notion of “performance” as unequivocally observable. Drawing upon traditional philosophical distinctions between behaviour and action, and interpretative, constructionist, situational, and relational traditions within the social sciences, the nature of performance is subjected to theoretical analysis. It is argued that performance cannot be taken as transparent evidence of learning. Rather the attribution of performance is itself the outcome of situated acts of interpretation, essentially contestable and negotiated, subject to reinterpretation and renegotiation. The key social processes by which such interpretation is accomplished will be shown to implicate issues of identity (and identity formation) and social practice (and its discursive production). The potential fruitfulness of the identity-practice model will be illustrated by applying it to the issue of graduate “employability”, in order to address problems with the conventional “skills” approach.     

What can subjective forgetting tell us about memory for childhood trauma?

In the present study, we examined the prevalence and predictors of subjective forgetting (i.e., self-reported amnesia) of child sexual abuse (CSA). Adults who, as children, were involved as victims in legal prosecutions were questioned about their CSA experiences, which had been documented in the 1980s, and about lost and recovered memory of those experiences. Males and individuals who experienced more severe abuse were more likely to report forgetting. The majority of individuals attributed their forgetting to active attempts to avoid thinking about the abuse. In contrast, when predictors of subjective forgetting were used to predict objective memory of abuse, more severe abuse and more extended legal involvement were associated with fewer memory errors. The differences between subjective and objective memory underscore the risks of using subjective measures to assess lost memory of abuse.     

Theories of spatial representations and reference frames: What can configuration errors tell us?

The issue of reference frame is central to theories of spatial representations. Various classifications have been made for different types of reference frames, along with prototypical research paradigms to distinguish between them. This article focuses on the configuration error paradigm proposed by Wang and Spelke (Cognition 77:215-250, 2000) that has been used to examine the nature of the spatial representations underlying object localization during self-movement. Three basic models of spatial memory and spatial updating are discussed, as well as the assumptions behind the configuration error paradigm, to distinguish between static representations, such as the traditional allocentric cognitive map and the egocentric snapshots, and dynamic representations, such as the egocentric updating system. Recent experimental findings are reexamined and shown to be consistent with multiple models, among which the egocentric-updating-and-reload model with an enduring egocentric component provides the simplest interpretations.     

What can self-disorders in schizophrenia tell us about the nature of subjectivity? A psychopathological investigation

The purpose of this article is to show how schizophrenia, understood as a distortion of the most intimate structures of subjectivity, illustrates the nature of subjectivity as such, while at the same time how philosophical considerations may help to understand schizophrenia. More precisely, schizophrenic experiences of self-alienation seem to reflect a congealing or concretization of a form of differentiation or potential alterity implicit in the dynamic nature of subjectivity. In other words, we propose that the structure of subjectivity includes potential divisions and fissures that condition the experiences of radical self-alienation seen in schizophrenia. In order to elucidate how this alterity emerges within the self in schizophrenia and in order to consider its conditions of possibility we examine the disorders of the self as described in phenomenological psychopathology. We especially use the work of the Japanese psychiatrists Mari Nagai, her teacher Bin Kimura, and the French psychiatrist Henry Ey, supplemented with clinical material from our own research. Finally, we shed light on the development of the psychotic symptoms such as hallucinations and delusions, which are understood as the expressions of a radical alterization (i.e., becoming other) of the self.     

What can neuroimaging meta-analyses really tell us about the nature of emotion?

In Vytal and Hamann (2010) we reported a neuroimaging meta-analysis that found that basic emotions can be distinguished by their brain activation correlates, in marked contrast to Lindquist et al.'s conclusions in the target article. Here, I discuss implications of these findings for understanding emotion, outline limitations of using meta-analyses and neuroimaging as the sole basis for deciding between emotion views, and suggest that these views are essentially compatible and could be adapted and combined into an integrated emotion framework.     

Relationship between field dependence-independence and the g factor: What can problem-solving strategies tell us?

IntroductionField dependence-independence (FDI) has been the focus of a great deal of research. However, it is generally studied in relation to either personality or the g factor, with far fewer studies of the interconnections between FDI, the g factor and problem-solving strategies.ObjectiveOur first aim was to study the relationship between FDI and the g factor. Our second was to explain this relationship by analysing problem-solving strategies.MethodOne hundred and seventy 14-year-old performed three tests: the GEFT, the D-70, and a second, prototype g-factor test that enabled us to identify which strategies they used.ResultsResults confirmed the classic link between FDI and the g factor, and attributed this link to greater use of the most efficient strategies.     

What can megastudies tell us about the orthographic structure of English words?

Although the majority of research in visual word recognition has targeted single-syllable words, most words are polysyllabic. These words engender special challenges, one of which concerns their analysis into smaller units. According to a recent hypothesis, the organization of letters into groups of successive consonants (C) and vowels (V) constrains the orthographic structure of printed words. So far, evidence has been reported only in French with factorial studies of relatively small sets of items. In the present study, we performed regression analyses on corpora of megastudies (English and British Lexicon Project databases) to examine the influence of the CV pattern in English. We compared hiatus words, which present a mismatch between the number of syllables and the number of groups of adjacent vowel letters (e.g., client), to other words, controlling for standard lexical variables. In speeded pronunciation, hiatus words were processed more slowly than control words, and the effect was stronger in low-frequency words. In the lexical decision task, the interference effect of hiatus in low-frequency words was balanced by a facilitatory effect in high-frequency words. Taken together, the results support the hypothesis that the configuration of consonant and vowel letters influences the processing of polysyllabic words in English.     

Early childhood experiences and current emotional distress: what do they tell us about aspiring psychologists?

Motivation underlying the career choice of mental health professionals may include a desire to resolve personal psychological distress from childhood or the need to continue the caretaking role held in the family (A. DiCaccavo, 2002; J. D. Guy, 1987). The authors examined whether psychology students whose future vocational aspirations lie in the clinical domain (N = 40) differed from psychology students with no clinical aspirations (N = 35) and from business students (N = 91) in reported childhood experiences and current psychological functioning. Psychology students who wanted to work in the clinical domain reported higher rates of perceived childhood sexual abuse and neglect as compared with both psychology students with no clinical aspirations and business students. They also reported more parentification experiences between the ages of 14 years and 16 years as compared with business students. There were no significant differences between groups in reported levels of current negative emotions.     

What can gender tell us about the pre-retirement experiences of elite distance runners in Finland?: A thematic narrative analysis

ObjectivesThis study explores gendered experiences of the mastery stage in endurance runners' athletic careers in terms of (a) key themes in this period of life, (b) retirement decision-making and (c) changes in athletic and runner identities.Design and methodTen male and nine female athletes aged between 25 and 62 participated in individual interviews. The data were analyzed via thematic narrative analysis.Results and conclusionGendered meanings permeate career decision-making and retirement patterns of Finnish runners. Female athletes reported many difficulties, including health problems, loneliness, societal pressure and lack of social support during the final years of their careers. These aspects were important reasons for them to start considering retirement from sport. Male athletes reported less social pressure and suggested that friendship in sport was a major reason for postponing retirement. Male athletes expressed more interest for coaching others, wherein women perceived themselves as incompetent and/or lacked time and interest for it. Running remained important for the majority of athletes after retirement and they anticipated or had continued regular running post-retirement.     

Adlerian-oriented early memory research: what does it tell us?

Of the different approaches to interpreting early memories (EMs), Adlerian-oriented EM research comparatively has shown a most substantial increase in the past 10 years. I examine all Adlerian-oriented EM research appearing from 1981 through 1990. The majority of the research provides a tentative base of support for Adler's (1931) views about EMs. However, several deficiencies in these investigations are identified (e.g., a lack of pilot studies), and some recommendations are made for future EM studies.
