What do bilingual infants actually hear? Evaluating measures of language input to bilingual‐learning 10‐month‐olds

Examining how bilingual infants experience their dual language input is important for understanding bilingual language acquisition. To assess these language experiences, researchers typically conduct language interviews with caregivers. However, little is known about the reliability of these parent reports in describing how bilingual children actually experience dual language input. Here, we explored the quantitative nature of dual language input to bilingual infants. Furthermore, we described some of the heterogeneity of bilingual exposure in a sample of French–English bilingual families. Participants were 21 families with a 10‐month‐old infant residing in Montréal, Canada. First, we conducted language interviews with the caregivers. Then, each family completed three full‐day recordings at home using the Language Environment Analysis recording system. Results showed that children’s proportion exposure to each language was consistent across the two measurement approaches, indicating that parent reports are reliable for assessing a bilingual child’s language experiences. Further exploratory analyses revealed three unique findings: (a) there can be considerable variability in the absolute amount of input among infants hearing the same proportion of input, (b) infants can hear different proportions of language input when considering infant‐directed versus overheard speech, (c) proportion of language input can vary by day, depending on who is caring for the infant. We conclude that collecting naturalistic recordings is complementary to parent‐report measures for assessing infant’s language experiences and for establishing bilingual profiles.

To master or perform? Exploring relations between achievement goals and conceptual change learning

Background. Research is needed to explore conceptual change in relation to achievement goal orientations and depth of processing. Aims. To address this need, we examined relations between achievement goals, use of deep versus shallow processing strategies, and conceptual change learning using a think‐aloud protocol. Sample and Method. Seventy‐three undergraduate students were assessed on their prior knowledge and misconceptions about Newtonian mechanics, and then reported their achievement goals and participated in think‐aloud protocols while reading Newtonian physics texts. Results. A mastery‐approach goal orientation positively predicted deep processing strategies, shallow processing strategies, and conceptual change. In contrast, a performance‐approach goal orientation did not predict either of the processing strategies, but negatively predicted conceptual change. A performance‐avoidance goal orientation negatively predicted deep processing strategies and conceptual change. Moreover, deep and shallow processing strategies positively predicted conceptual change as well as recall. Finally, both deep and shallow processing strategies mediated relations between mastery‐approach goals and conceptual change. Conclusions. Results provide some support for Dole and Sinatra's (1998) Cognitive Reconstruction of Knowledge Model of conceptual change but also challenge specific facets with regard to the role of depth of processing in conceptual change.     

Can dogs count?

Numerical competencies have been thoroughly examined in several species, yet relatively few studies have examined such processes in the domestic dog. In an initial experiment, procedures from numerical studies of chimpanzees (0010 and 0015) were adapted for use with 27 domestic dogs. Subjects in these experiments watched as different quantities of food were sequentially dropped into each of two bowls. The subjects were then allowed to select and consume the contents of one of the bowls. Although dogs excelled in a 1 vs 0 condition, their performance failed to significantly surpass chance across all other ratios. In a second experiment with a single subject (a rough collie named Sedona), the procedure was revised so that non-food stimuli were presented simultaneously to the dog on two magnet boards. If Sedona chose the board with the majority of the items, she was rewarded with a piece of food hidden underneath the board. If she made an incorrect choice, she received no reinforcement. Interestingly, Sedona's performance far exceeded that of the dogs in Experiment 1. Implications of these findings for the study of domestic dogs are discussed.     

Intimate partner violence and the capacity and desire for self-control

ABSTRACT

According to Tittle, the effect of self-control on one’s criminal offending is a product of both an individual’s capacity to exercise self-control as well as their desire to do so. The present study utilized self-report data gathered at a large urban university in Florida (n = 1,307) to test both the independent and interactive effects of self-control capacity and self-control desire on intimate partner violence (IPV) perpetration. The study suggests that while both capacity and desire for control have effects on one’s likelihood of reporting IPV perpetration, these effects were independent of each other and no evidence of interaction between to two were observed.     

Examining the Relationship Between Mental Toughness and Imagery Use

Mental toughness is an important characteristic contributing to athletic excellence (Jones, Hanton, & Connaughton, 2007), yet little quantitative research has examined how psychological skills such as imagery contribute to its development. The present study investigated the relationship between mental toughness with imagery in a sample of varsity athletes (N = 151, M_age = 20.70). Hierarchical multiple regression analyses revealed that imagery use significantly predicted mental toughness. Specifically, motivational general-mastery imagery emerged as the strongest individual predictor for all dimensions of mental toughness (β = .45-.53), thus, providing support for imagery use as a potential strategy for developing or enhancing mental toughness in athletes.     

Perceptual grouping in haptic search: The influence of proximity, similarity, and good continuation

We conducted a haptic search experiment to investigate the influence of the Gestalt principles of proximity, similarity, and good continuation. We expected faster search when the distractors could be grouped. We chose edges at different orientations as stimuli because they are processed similarly in the haptic and visual modality. We therefore expected the principles of similarity and good continuation to be operational in haptics as they are in vision. In contrast, because of differences in spatial processing between vision and haptics, we expected differences for the principle of proximity. In haptics, the Gestalt principle of proximity could operate at two distinct levels-somatotopic proximity or spatial proximity-and we assessed both possibilities in our experiments. The results show that the principles of similarity and good continuation indeed operate in this haptic search task. Neither of our proximity manipulations yielded effects, which may suggest that grouping by proximity must take place before an invariant representation of the object has formed.

How visual and semantic information influence learning in familiar contexts

Previous research using the contextual cuing paradigm has revealed both quantitative and qualitative differences in learning depending on whether repeated contexts are defined by letter arrays or real-world scenes. To clarify the relative contributions of visual features and semantic information likely to account for such differences, the typical contextual cuing procedure was adapted to use meaningless but nevertheless visually complex images. The data in reaction time and in eye movements show that, like scenes, such repeated contexts can trigger large, stable, and explicit cuing effects, and that those effects result from facilitated attentional guidance. Like simpler stimulus arrays, however, those effects were impaired by a sudden change of a repeating image's color scheme at the end of the learning phase (Experiment 1), or when the repeated images were presented in a different and unique color scheme across each presentation (Experiment 2). In both cases, search was driven by explicit memory. Collectively, these results suggest that semantic information is not required for conscious awareness of context-target covariation, but it plays a primary role in overcoming variability in specific features within familiar displays.
