A developmental study of the influence of task characteristics on motor overflow

Motor overflow refers to involuntary movement or muscle activity that may coincide with voluntary movement. This study examined factors influencing motor overflow in 17 children (8-11 years), and 17 adults (18-35 years). Participants performed a finger pressing task by exerting either 33% or 66% of their maximal force output using their dominant or non-dominant hand. Attention was manipulated by tactile stimulation to one or both hands. Overflow relative to the target force was greater in children compared to adults, and at the lower target force for both groups, but was not influenced by attentional stimulation. Childhood overflow was greater when the left-hand performed the task. Although an immature motor system may underlie an inability to suppress involuntary movement, childhood overflow may provide motor stabilization.     

Diffusion of Innovation Theory: A Bridge for the Research‐Practice Gap in Counseling

This article presents a diffusion of innovation theory‐based framework for addressing the gap between research and practice in the counseling profession. The author describes the nature of the research‐practice gap and presents an overview of diffusion of innovation theory. On the basis of the application of several major postulates of diffusion of innovation theory to the research‐practice gap, several theory‐based research practices and questions are proposed.     

To Tell or Not to Tell: Disclosure and the Narrative Self

ABSTRACT Drawing from a narrative identity framework, we present the results of three studies examining the nature of what people do and do not disclose about their life experiences. Across three studies, our findings indicate that (1) the major difference in what people do and do not disclose concerns the emotionality of the events and whether or not the events are transgressions; (2) for everyday memorable events, increased negative emotion is associated with greater likelihood of disclosure; but (3) for more important and/or longer retained events, increased negative and decreased positive emotion were associated with lower likelihoods of disclosure. We also found that socioemotional consequences are an important reason for nondisclosure of important past experiences and are predictably related to the extent to which events induce positive and negative emotions. Findings are considered in terms of their implications for narrative identity.     

The relationship between knowing a word and reading it aloud in children’s word reading development

This experiment examined the item-level relationship between 7-year-olds’ ability to read words aloud and their knowledge of the same words in the oral domain. Two types of knowledge were contrasted: familiarity with the phonological form of the word (lexical phonology), measured by auditory lexical decision, and semantic knowledge, measured by a definitions task. Overall, there was a robust relationship between word knowledge and reading aloud success. The association was stronger when words contained irregular spelling-sound correspondences. There was no evidence that a deeper or more semantic knowledge of words was more closely related to reading aloud success beyond the association between reading success and familiarity with the phonological form of the same words. This finding is not compatible with models that see semantics as contributing directly to the reading aloud process, at least during the relatively early stages of reading development. More critical was whether or not a word was considered a lexical item, as indexed by auditory lexical decision performance.     

Strength-based criterion shifts in recognition memory

In manipulations of stimulus strength between lists, a more lenient signal detection criterion is more frequently applied to a weak than to a strong stimulus class. However, with randomly intermixed weak and strong test probes, such acriterion shift often does not result. A procedure that has yieldeddelay-based within-list criterion shifts was applied to strength manipulations in recognition memory for categorized word lists. When participants made semantic ratings about each stimulus word, strength-based criterion shifts emerged regardless of whether words from pairs of categories were studied in separate blocks (Experiment 1) or in intermixed blocks (Experiment 2). In Experiment 3, the criterion shift persisted under the semantic-rating study task, but not under rote memorization. These findings suggest that continually adjusting the recognition decision criterion is cognitively feasible. They provide a technique for manipulating the criterion shift, and they identify competing theoretical accounts of these effects.     

Beginning readers activate semantics from sub-word orthography

Two experiments assessed whether 7-year-old children activate semantic information from sub-word orthography. Children made category decisions to visually-presented words, some of which contained an embedded word (e.g., hip in ship). In Experiment 1 children were slower and less accurate to classify words if they contained an embedded word related in meaning to the category (e.g., slower to reject ship as a ‘body part’ than an ‘animal’), especially when the embedded word was higher in frequency than the carrier word. This demonstrates that young children activate semantic information from sub-word orthographic representations, and that they do so from the relatively early stages of learning to read. Experiment 2 replicated this effect. Furthermore, we observed semantic interference regardless of whether the embedded word shared its pronunciation with the carrier (e.g., the hip in ship) or not (e.g., the crow in crown), and regardless of its position within the carrier, suggesting that interference was not dependent on phonological mediation. These findings show that by 7-years-of age, children have begun to establish an orthographic system that is capable of activating sub-word orthographic patterns, strong enough to connect with meaning, when reading words silently.     

Thomas Aquinas and the Potential Catholic Integration of a Dynamic Occasionalist Understanding of Grace

Starting out from John Barclay's Lutheran‐inclined, actualist reading of the in‐breaking quality of grace and the Spirit in Paul, this article asks how a Catholic theology of grace – typically more focused on identifying the relatively stable structures and effects of grace – might with integrity learn from the Barclayan‐Lutheran‐Pauline difference. By pursuing a close, four‐step reading of Thomas Aquinas' theology of grace, as that appears in the Summa Theologiæ and his lectures on the Pauline epistles, the article demonstrates that just such a Catholic appropriation of a more dynamic graced actualism is indeed possible; one which leads, with dynamic integrity, to a deepened understanding, articulation and practice of core Catholic instincts rather than to their reduction or distortion.     

Intersubjectivity,object relations theory,and empirical evidence from mother-infant interactions

The work of John Bowlby and his associates on the development of the infant's attachment to his or her parents in the second half of the first year reflects the fruitfulness of an integration of psychoanalytic insights and empirical research. In line with this approach, this paper considers the mother-infant relationship in the first few months from two perspectives: that of the British School of Object Relations and that of the theory of Intersubjectivity, set out initially within developmental psychology and, more recently, developed within systems theory. These views are considered in the light of evidence from two sources. First, a series of experimental studies is described employing disruptions to both the form and the timing of communication between 6- to 12-week-old infants and their mothers. This work illustrates the sensitivity of young infants to the quality of their interpersonal engagements and, also, the contribution of the infant to the regulation of interactions with others. Second, evidence is presented from a prospective study of the effects of maternal depression in the postnatal period on infant development. This work shows the possible longer term consequences for the infant of early disturbances in the mother-infant relationship. Infants of postnatally depressed women were found to be more insecurely attached to their mothers, were more likely to have mild behavioral problems (especially sleep disturbance), and showed poorer outcome on Object Concept tasks at 18 months. These effects occurred despite the fact that the mother had recovered from depression by 3 months postpartum.
