Young children’s age-of-acquisition estimates for spoken words

This study was concerned with the impact of stimulus familiarity on young children's ability to recognize spoken words and make explicit judgments about them. In Experiment 1, 5-year-olds made age-of-acquisition (AOA) estimates for a set of words that were very similar to estimates made by older children and adults. In Experiment 2, young children's picture recognition, mispronunciation detection, and vocabulary monitoring performance all varied systematically with these AOA estimates and with a stimulus-type (intact-mispronounced) manipulation. Subjective AOA estimates (whether from children or from adults) proved to be a better predictor of performance than did two objective familiarity measures and subjective imageability. These results point to considerable metalexical knowledge on the part of young children or explicit sensitivity regarding their own vocabulary knowledge. In addition, the results lend some support to the notion that actual AOA contributes to subjective AOA estimates.     

TOWARD THE DEVELOPMENT OF STRUCTURED CRITERIA FOR INTERPRETATION OF FUNCTIONAL ANALYSIS DATA

Using functional analysis results to prescribe treatments is the preferred method for developing behavioral interventions. Little is known, however, about the reliability and validity of visual inspection for the interpretation of functional analysis data. The purpose of this investigation was to develop a set of structured criteria for visual inspection of multielement functional analyses that, when applied correctly, would increase interrater agreement and agreement with interpretations reached by expert consensus. In Study 1, 3 predoctoral interns interpreted functional analysis graphs, and interrater agreement was low (M = .46). In Study 2, 64 functional analysis graphs were interpreted by a panel of experts, and then a set of structured criteria were developed that yielded interpretive results similar to those of the panel (exact agreement = .94). In Study 3, the 3 predoctoral interns from Study 1 were trained to use the structured criteria, and the mean interrater agreement coefficient increased to .81. The results suggest that (a) the interpretation of functional analysis data may be less reliable than is generally assumed, (b) decision-making rules used by experts in the interpretation of functional analysis data can be operationalized, and (c) individuals can be trained to apply these rules accurately to increase interrater agreement. Potential uses of the criteria are discussed.     

Women's development through personal knowing

Striking intuitive experiences may influence women to become active in working for social and political change and to pursue nontraditional career goals. These moments of insight, referred to a experiences of personal knowing, are the subject of this qualitative study of 100 excerpts from women's memoirs, journals and autobiographies. Personal knowing in these narratives includes an important personal insight, strong affect, an altered state of consciousness, suddenness and physical sensations. The first person narratives studied demonstrate that women spontaneously write about personal knowing to explain their motivations, life choices and self-development.Personal knowing experiences, which are often considered trivial or exceptional, are discussed as significant developmental events which combine cognition and affect and may occur throughout the life cycle.     

An examination of word frequency and neighborhood density in the development of spoken-word recognition

In this study, the effects of word-frequency and phonological similarity relations in the development of spoken-word recognition were examined. Seven-, 9-, and 11-year-olds and adults listened to increasingly longer segments of high- and low-frequency monosyllabic words with many or few word neighbors that sounded similar (neighborhood density). Older children and adults required less of the acoustic-phonetic information to recognize words with few neighbors and low-frequency words than did younger children. Adults recognized high-frequency words with few neighbors on the basis of less input than did all three of the children’s groups. All subjects showed a higher proportion of different-word guesses for words with many versus few neighbors. A frequency × neighborhood density interaction revealed that recognition is facilitated for high-frequency words with few versus many neighbors; the opposite was found for low-frequency words. Results are placed within a developmental framework on the emergence of the phoneme as a unit in perceptual processing.     

Delimiting Family in Syntheses of Research on Childhood Chronic Conditions and Family Life

Synthesis of family research presents unique challenges to investigators who must delimit what will be included as a family study in the proposed review. In this paper, the authors discuss the conceptual and pragmatic challenges of conducting systematic reviews of the literature on the intersection between family life and childhood chronic conditions. A proposed framework for delimiting the family domain of interest is presented. The framework addresses both topical salience and level of relevance and provides direction to future researchers, with the goal of supporting the overall quality of family research synthesis efforts. For users of synthesis studies, knowledge of how investigators conceptualize the boundaries of family research is important contextual information for understanding the limits and applicability of the results.     

From women to objects: Appearance focus, target gender, and perceptions of warmth, morality and competence

Most literally, objectification refers to perceiving a person as an object, and consequently, less than fully human. Research on perceptions of humanness and the stereotype content model suggests that humanness is linked to perceptions of warmth, morality and competence. Merging these insights with objectification theory, we hypothesized that focusing on a woman's, but not a man's, appearance should induce objectification, and thus reduce perceptions of these characteristics. In three studies, females, but not males, were perceived as less competent (Studies 2 and 3) and less warm and moral (Studies 1, 2 and 3) when participants were instructed to focus on their appearance. These findings support our position and help rule out stereotype activation as an alternative explanation to dehumanization. Further, they generalized to targets of different races, familiarity, physical attractiveness and occupational status. Implications for gender inequity and the perpetuation of objectification of women are discussed.     

Death awareness and body–self dualism: A why and how of afterlife belief

Belief in life after death offers potential comfort in the face of inevitable death. However, afterlife belief likely requires not only an awareness of death but also body–self dualism—the perception that the self (e.g., the mind) is distinct from the physical, undeniably mortal, body. In turn, we hypothesized that mortality salience (MS) should heighten afterlife belief only when dualism is facilitated. Study 1 found that MS increased belief for people high, relative to low, in trait mind–body dualism. In Study 2, MS only increased belief when people first wrote about their thoughts and personality, which a pilot study confirmed facilitated dualistic belief, relative to thinking about the physical self. Study 3 used the brain–computer interface technology to induce a dualistic experience: MS increased belief when participants accurately “typed” without the use of their external body (i.e., no hands). Together, these findings support the position that mortality awareness and body–self dualism constitute a “why” and “how” of afterlife belief. Copyright © 2015 John Wiley & Sons, Ltd.     

The relationship between differential stimulus relatedness and implicit measure effect sizes

Implicit measures have been hypothesized to allow researchers to ascertain the existence and strength of relations between stimuli, often in the context of research on attitudes. However, little controlled behavioral research has focused on whether stimulus relations, and the degree of relatedness within such relations, are indexed by implicit measures. The current study examined this issue using a behavior‐analytic implicit‐style stimulus relation indexing procedure known as the Function Acquisition Speed Test (FAST). Using a matching‐to‐sample (MTS) procedure to train stimulus equivalence relations between nonsense syllables, the number of iterations of the procedure was varied across groups of participants, hence controlling stimulus relatedness in the resulting equivalence relations. Following final exposure to the MTS procedure, participants completed a FAST. Another group of participants was exposed to a FAST procedure with word pairs of known relatedness. Results showed that increasing relatedness resulted in a linear increase in FAST effect size. These results provide the first direct empirical support for a key process‐level assumption of the implicit literature, and offer a behavior‐analytic paradigm within which to understand these effects. These results also suggest that the FAST may be a viable procedure for the quantification of emergent stimulus relations in stimulus equivalence training.     

What explains the correlation between growth in vocabulary and grammar? New evidence from latent change score analyses of simultaneous bilingual development

A close relationship between children's vocabulary size and the grammatical complexity of their speech is well attested but not well understood. The present study used latent change score modeling to examine the dynamic relationships between vocabulary and grammar growth within and across languages in longitudinal data from 90 simultaneous Spanish–English bilingual children who were assessed at 6‐month intervals between 30 and 48 months. Slopes of vocabulary and grammar growth were strongly correlated within each language and showed moderate or nonsignificant relationships across languages. There was no evidence that vocabulary level predicted subsequent grammar growth or that the level of grammatical development predicted subsequent vocabulary growth. We propose that a common influence of properties of input on vocabulary and grammatical development is the source of their correlated but uncoupled growth. An unanticipated across‐language finding was a negative relationship between level of English skill and subsequent Spanish growth. We propose that the cultural context of Spanish–English bilingualism in the US is the reason that strong English skills jeopardize Spanish language growth, while Spanish skills do not affect English growth.
