Can infants' object concepts be trained?

Decades of research and debate on the origins of object permanence in infancy have contrasted various types of learning with possible innate contributions. A recent paper by Johnson et al. adds a new perspective to this debate by reporting that even very brief training periods can dramatically influence infants' persisting object representations. Such training studies have the potential to constrain 'nature versus nurture' debates in novel ways, although important challenges remain.     

Can phonemic awareness be trained in kindergarten?

The effect of a training program designed to develop phonemic awareness skills in kindergarten was assessed in a study involving three experimental groups and two control groups. The degree of structure imposed upon the program was varied in the experimental groups. One control group was trained in non-verbal auditory discrimination, and the second control group followed the ordinary preschool program during the 6–8 week observational period. A clear improvement in the ability to segment and blend three-phoneme words was observed in the highly structured training cohdition, especially among the children with poor pre-test performance, while no clear changes from pre- to post-test were found in the other groups. It was concluded that phonemic awareness can be developed in prereaders outside the context of formal reading instruction.     

Can Ziskin withstand his own criticisms? problems with his model of cross-examination

Ziskin has mounted a concerted attack on the scientific basis of psychology and psychiatry and their ability to provide expertise to the courts. He has assailed both the clinical methods and conclusions rendered by these mental health professionals. To rebut expert testimony, Ziskin has proposed general principles of cross-examination. We discuss the limitations of this model and provide an initial study of its effectiveness.     

Changed subject or wrong subject?

Abstract

In a provocative and an interesting article, Ogden (1995) argues that the focus of health psychology has changed. Early in the century, theorists regarded the individual as a passive responder to external events. Later, emphasis on the environment, made the individual a passive recipient of external events. Current theories emphasize individual control over the environment in an “intra-active” modality. Thus, as Ogden argues, theory has historical significance and the theory is data that describes thought at a particular point in time. Further, data are the product of methodology and the selection of methods must also be considered another piece of data.     

Can young preschool children be trained to perform percept deprivation tasks?

Young preschool children aged 2 and 3 years were exposed to a novel paradigm designed to train visual perception skills. The results indicate that children of this age can be trained to perform a percept deprivation task that requires a sophisticated understanding of attention not normally mastered until 3.5-4 years. Results are discussed with reference to engagement, a precursor to an adult-like understanding of perception.     

Can a machine tickle?

It has been observed at least since the time of Aristotle that people cannot tickle themselves, but the reason remains elusive. Two sorts of explanations have been suggested. Theinterpersonal explanation suggests that tickling is fundamentally interpersonal and thus requires another person as the source of the touch. Thereflex explanation suggests that tickle simply requires an element of unpredictability or uncontrollability and is more like a reflex or some other stereotyped motor pattern. To test these explanations, we manipulated the perceived source of tickling. Thirty-five subjects were tickled twice-once by the experimenter, and once, they believed, by an automated machine. The reflex view predicts that our “tickle machine” should be as effective as a person in producing laughter, whereas the interpersonal view predicts significantly attenuated responses. Supporting the reflex view, subjects smiled, laughed, and wiggled just as often in response to the machine as to the experimenter. Self-reports of ticklishness were also virtually identical in the two conditions. Ticklish laughter evidently does not require that the stimulation be attributed to another person, as interpersonal accounts imply.     

Difficulties in auditory organization as a cause of reading backwardness? An auditory neuroscience perspective

Over 30 years ago, it was suggested that difficulties in the ‘auditory organization’ of word forms in the mental lexicon might cause reading difficulties. It was proposed that children used parameters such as rhyme and alliteration to organize word forms in the mental lexicon by acoustic similarity, and that such organization was impaired in developmental dyslexia. This literature was based on an ‘oddity’ measure of children's sensitivity to rhyme (e.g. wood, book, good) and alliteration (e.g. sun, sock, rag). The ‘oddity’ task revealed that children with dyslexia were significantly poorer at identifying the ‘odd word out’ than younger children without reading difficulties. Here we apply a novel modelling approach drawn from auditory neuroscience to study the possible sensory basis of the auditory organization of rhyming and non‐rhyming words by children. We utilize a novel Spectral‐Amplitude Modulation Phase Hierarchy (S‐AMPH) approach to analysing the spectro‐temporal structure of rhyming and non‐rhyming words, aiming to illuminate the potential acoustic cues used by children as a basis for phonological organization. The S‐AMPH model assumes that speech encoding depends on neuronal oscillatory entrainment to the amplitude modulation (AM) hierarchy in speech. Our results suggest that phonological similarity between rhyming words in the oddity task depends crucially on slow (delta band) modulations in the speech envelope. Contrary to linguistic assumptions, therefore, auditory organization by children may not depend on phonemic information for this task. Linguistically, it is assumed that ‘book’ does not rhyme with ‘wood’ and ‘good’ because the final phoneme differs. However, our auditory analysis suggests that the acoustic cues to this phonological dissimilarity depend primarily on the slower amplitude modulations in the speech envelope, thought to carry prosodic information. Therefore, the oddity task may help in detecting reading difficulties because phonological similarity judgements about rhyme reflect sensitivity to slow amplitude modulation patterns. Slower amplitude modulations are known to be detected less efficiently by children with dyslexia.     

Can Psychoanalysis be a Science?

This essay proposes to examine a limited number of critical assessments regarding the scientific status of psychoanalysis with reference to intents and purposes, claims and disclaimers, contrasting views of what constitutes a science and the nature of scientific thinking and how these might apply to psychoanalysis epistemologically. It assumes a certain degree of familiarity with criticisms that have been leveled against psychoanalysis from those who insist on absolutist testing for what some call true science, particularly on the part of those who are not practitioners of the art. It wonders about the concern with scientizing by those who actually practice it, or value it in some way or another. It suggests an open minded approach without premature or even warranted closure on the subject of human beings and of ways of getting to know them, let alone understanding them and perhaps being of help to them.

Can pupillometry index auditory attentional capture in contexts of active visual processing?

The rare presentation of a sound that deviates from the auditory background tends to capture attention, which is known to impede cognitive functioning. Such disruption is usually measured using performance on a concurrent visual task. Growing evidence recently showed that the pupillary dilation response (PDR) could index the attentional response triggered by a deviant sound. Given that the pupil diameter is sensitive to several vision-related factors, it is unclear whether the PDR could serve to study attentional capture in such contexts. Hence, the present study aimed at verifying whether the PDR can be used as a proxy for auditory attentional capture while a visual serial recall task (Experiment 1) or a reading comprehension task (Experiment 2) – respectively producing changes in luminance and gaze position – is being performed. Results showed that presenting a deviant sound within steady-state standard sounds elicited larger PDRs than a standard sound. Moreover, the magnitude of these PDRs was positively related to the amount of performance disruption produced by deviant sounds in Experiment 1. Performance remained unaffected by the deviants in Experiment 2, thereby implying that the PDR may be a more sensitive attention-capture index than behavioural measures. These results suggest that the PDR can be used to assess attentional capture by a deviant sound in contexts where the pupil diameter can be modulated by the visual environment.
