Preference for language in early infancy: the human language bias is not speech specific

Fundamental to infants' acquisition of their native language is an inherent interest in the language spoken around them over non-linguistic environmental sounds. The following studies explored whether the bias for linguistic signals in hearing infants is specific to speech, or reflects a general bias for all human language, spoken and signed. Results indicate that 6-month-old infants prefer an unfamiliar, visual-gestural language (American Sign Language) over non-linguistic pantomime, but 10-month-olds do not. These data provide evidence against a speech-specific bias in early infancy and provide insights into those properties of human languages that may underlie this language-general attentional bias.     

The Personality Characteristics of Methodist Ministers: Feminine Men and Masculine Women?

A detailed questionnaire was mailed to every Methodist minister engaged in circuit ministry in Great Britain. Each of the 1,339 respondents completed the Revised Eysenck Personality Questionnaire (EPQR-S). The male ministers recorded lower psychoticism scores than the male population norms. The female ministers recorded lower neuroticism scores than the female population norms. These findings support the view that ministry may appeal particularly to men who value and display the tender-minded personality characteristics associated with femininity and to women who value and display the stable personality characteristics associated with masculinity. Implications of these findings for ministry are discussed.     

How Far Can Support Go? Supported Supervisors’ Performance and Subordinate Dedication

Purpose

The present study builds on prior research involving organizational support theory and the trickle-down effects of supervisors’ perceived organizational support (POS). We examine benefits of supervisor POS for the supervisors themselves (enhanced affective commitment and in-role performance), and a behavioral mechanism through which supervisors’ POS may lead to subordinate dedication, a multifaceted conceptualization of performance.

Design/Methodology/Approach

Using three sources of data (from 139 human resource professionals, their 47 supervisors, and the 22 bosses of their supervisors) we assessed the hypothesized relationships using multilevel path modeling.

Findings

Supervisors’ POS related positively to supervisors’ affective commitment to their organization, resulting in better supervisor in-role performance two months later. Also, having better performing supervisors resulted in more dedication by employees in the form of extra-role performance, as rated by their supervisor 2 months later, and extra hours worked.

Implications

It appears providing organizational support to supervisors may result in beneficial outcomes for the supervisors and the organization in terms of supervisors’ enhanced emotional attachment to the company, and better performance in their job, with consequences for subordinate dedication in terms of extra hours worked and extra-role performance.

Originality/Value

These findings contribute to organizational support theory by showing initial evidence that supervisor in-role performance can serve as an explanatory mechanism through which supervisors’ POS trickles down to aid subordinates.

     

Microaggressions: The experience of individuals with mental illness

The main objective of the study was to investigate the types of microaggressions experienced by individuals with mental illness (MI) based on this marginalized group status. This study included 4 focus groups, comprised of 18 individuals diagnosed with MI(es). The researchers qualitatively identified four themes (a) conveying stereotypes against individuals with MI (i.e. assumptions of inferiority, seeking attention or being dramatic, assumptions of coldness, bringing MI upon themselves, and using MI as an excuse), (b) invalidating the experience of having a MI (i.e. doubting existence, doubting severity, and avoiding acknowledgment of the MI), (c) defining a person by their disorder, and (d) misuse of terminology. Participants revealed the main perpetrators (i.e. family, friends, and professionals) of the microaggressions. The researchers discuss: how the identified themes compare to the three categories of microaggressions (i.e. microinsults, microinvalidations, and microassaults); similarities and differences between the current results and previously identified racial, gender, and sexual orientation microaggressions perpetrated in daily interactions and in therapeutic settings; and the perpetrators of microaggressions as they relate to prejudicial attitudes and social distance. Finally, the authors make recommendations for practitioners and researchers.     

Cross‐Situational Learning of Minimal Word Pairs

Cross‐situational statistical learning of words involves tracking co‐occurrences of auditory words and objects across time to infer word‐referent mappings. Previous research has demonstrated that learners can infer referents across sets of very phonologically distinct words (e.g., WUG, DAX), but it remains unknown whether learners can encode fine phonological differences during cross‐situational statistical learning. This study examined learners’ cross‐situational statistical learning of minimal pairs that differed on one consonant segment (e.g., BON–TON), minimal pairs that differed on one vowel segment (e.g., DEET–DIT), and non‐minimal pairs that differed on two or three segments (e.g., BON–DEET). Learners performed above chance for all pairs, but performed worse on vowel minimal pairs than on consonant minimal pairs or non‐minimal pairs. These findings demonstrate that learners can encode fine phonetic detail while tracking word‐referent co‐occurrence probabilities, but they suggest that phonological encoding may be weaker for vowels than for consonants.     

Spacing Simultaneously Promotes Multiple Forms of Learning in Children's Science Curriculum

The spacing effect refers to the robust finding that long‐term memory is promoted when learning events are distributed in time rather than massed in immediate succession. The current study extended research on the spacing effect by examining whether spaced learning schedules can simultaneously promote multiple forms of learning, such as memory and generalization, in the context of an educational intervention. Thirty‐six early elementary school‐aged children were presented with science lessons on one of three schedules: massed, clumped, and spaced. At a 1‐week delayed test, children in the spaced condition demonstrated improvements in both memory and generalization, significantly outperforming children in the other conditions. However, there was no observed relationship between children's memory performance and generalization performance. The current study highlights directions for future research and contributes to a growing body of work demonstrating the benefits of spaced learning for educational curriculum.

Finding the good in the bad: age and event experience relate to the focus on positive aspects of a negative event

All lives contain negative events, but how we think about these events differs across individuals; negative events often include positive details that can be remembered alongside the negative, and the ability to maintain both representations may be beneficial. In a survey examining emotional responses to the 2013 Boston Marathon bombings, the current study investigated how this ability shifts as a function of age and individual differences in initial experience of the event. Specifically, this study examined how emotional importance (i.e. self-reported emotional arousal and personal significance), involvement (i.e. self and friend/family involvement in the 2013 Boston Marathon and self-involvement in prior marathons), and self-reported surprise upon hearing about the event related to the tendency to report focusing on the negative and positive aspects of the bombings. Structural equation models revealed that while greater emotional importance and surprise were associated with a greater focus on negative elements, involvement and age were associated with increased consideration of positive aspects. Further, emotional importance was more strongly related to an increased focus on negative aspects for young adults and an increased focus on positive aspects for older adults, highlighting a tendency for older adults to enhance positive features of an otherwise highly negative event.     

A meta‐analytic review of tipping compensation practices: An agency theory perspective

Tipping represents a form of compensation valued at over $50 billion a year in the United States alone. Tipping can be used as an incentive mechanism to reduce a principal–agent problem. An agency problem occurs when the interests of a principal and agent are misaligned, and it is challenging for the principal to monitor or control the activities of the agent. However, past research has been limited in the investigation of the extent to which tipping is effective at addressing this problem. Following an examination of 74 independent studies with 12,271 individuals, meta‐analytic results indicate that there is a small, positive relation between service quality and percentage of a bill tipped ( = .15 without outliers). Yet, in support of the idea behind tipping, relative weights analyses illustrate that service quality was a stronger predictor of percentage of the bill tipped than food quality, frequency of patronage, and dining party size. Evidence also suggests that racial minority servers tend to be tipped less than White servers (Cohen's d = .17), and women tend to be tipped more than men (Cohen's d = .15). Still, given the magnitude of the effect, one might question if tipping is an effective compensation practice to reduce the principal–agent problem. We discuss theoretical and practical implications for future research.     

Reduction of Health Care Costs and Improved Appropriateness of Incoming Test Orders: the Impact of Genetic Counselor Review in an Academic Genetic Testing Laboratory

The goal of this study was to evaluate the impact of genetic counselor (GC) review of incoming test orders received in an academic diagnostic molecular genetics laboratory. The GC team measured the proportion of orders that could be modified to improve efficiency or sensitivity, tracked provider uptake of GC proposed testing changes, and calculated the health care dollar savings resulting from GC intervention. During this 6-month study, the GC team reviewed 2367 incoming test orders. Of these, 109 orders (4.6%) were flagged for review for potentially inefficient or inappropriate test ordering. These flagged orders corresponded to a total of 51 cases (1–5 orders for each patient), representing 54 individuals and including 3 sibling pairs. The GC team proposed a modification for each flagged case and the ordering providers approved the proposed change for 49 of 51 cases (96.08%). For the 49 modifications, the cost savings totaled $98,750.64, for an average of $2015.32 saved per modification. This study provides evidence of the significant contribution of genetic counselors in a laboratory setting and demonstrates the benefit of laboratories working with ordering providers to identify the best test for their patients. The review of test orders by a genetic counselor both improves genetic test ordering strategies and decreases the amount of health care dollars spent on genetic testing.     

The song,not the singer: Infants prefer to listen to familiar songs,regardless of singer identity

Parent's infant-directed vocalizations are highly dynamic and emotive compared to their adult-directed counterparts, and correspondingly, more effectively capture infants’ attention. Infant-directed singing is a specific type of vocalization that is common throughout the world. Parents tend to sing a small handful of songs in a stereotyped way, and a number of recent studies have highlighted the significance of familiar songs in young children's social behaviors and evaluations. To date, no studies have examined whether infants’ responses to familiar versus unfamiliar songs are modulated by singer identity (i.e., whether the singer is their own parent). In the present study, we investigated 9- to 12-month-old infants’ (N = 29) behavioral and electrodermal responses to relatively familiar and unfamiliar songs sung by either their own mother or another infant's mother. Familiar songs recruited more attention and rhythmic movement, and lower electrodermal levels relative to unfamiliar songs. Moreover, these responses were robust regardless of whether the singer was their mother or a stranger, even when the stranger's rendition differed greatly from their mothers’ in mean fundamental frequency and tempo. Results indicate that infants’ interest in familiar songs is not limited to idiosyncratic characteristics of their parents’ song renditions, and points to the potential for song as an effective early signifier of group membership.
