Naming products is quite prevalent in American culture; however, we are not aware of any consumer research that explores the effects of this phenomenon. Across three studies, we demonstrate that when consumers name products, their evaluations of those products increase (e.g., attitudes, purchase intentions, and willingness to accept). We find that name fit and creativity as well as subsequent psychological ownership drive this effect. We also demonstrate that the naming effect is quite robust—replicating across multiple products, presentation formats, and populations as well as persisting over time. These results contribute to consumer research by opening up a new substantive line of inquiry into the effects of naming products.  相似文献

This study examined whether baseline trauma patient characteristics and randomized participation in 1 of 2 brief interventions predicted changes in alcohol use at 6 months postintervention. Higher total Alcohol Use Disorders Identification Test (AUDIT) scores predicted greater changes, and specific AUDIT items were significant predictors.  相似文献

The current study employed a randomized controlled trial to evaluate the use of peer tutoring and fluency-based instruction to increase mathematics fluency with addition and subtraction computation skills. Forty-one elementary school students between the ages of eight and 12 years participated in the 8-week study using cross-age peer tutoring, Say All Fast Minute Every Day Shuffled, frequency building, and the morningside math facts curriculum (Johnson in Morningside mathematics fluency: math facts (vol 1–6; curriculum program), Morningside Press, Seattle, 2008). Pre- and post-test measures of mathematics fluency and calculation were conducted with all participants. A measure of social skills and competing problem behaviors was also conducted at pre- and post-testing to evaluate any additional effects of the peer tutoring model. The results demonstrated a statistically significant difference between groups on measures of mathematics fluency, with the experimental group demonstrating significantly higher scores than the control group at post-testing. There were no significant differences between groups on measures of social skills and competing problem behaviors or calculation. The findings indicate that cross-age peer tutoring and fluency-based instruction resulted in positive outcomes for tutees in the mathematics domain, specifically mathematics fluency.  相似文献

Although there is a well-established connection between father involvement and children’s positive behavioral development in general, this relation has been understudied in more vulnerable and high-risk populations. The aims of this study were to examine how the quantity (i.e., the amount of shared activities) and quality (i.e., perceived quality of the father-child relationship) of father involvement are differently related to internalizing and externalizing behavior problems among preadolescents at risk of maltreatment and test if these associations are moderated by father type and child maltreatment. A secondary data analysis was conducted using data from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN). Generalized estimating equations analysis was performed on a sample of 499 preadolescents aged 12 years. The results indicated that higher quality of father involvement was associated with lower levels of internalizing and externalizing behavior problems whereas greater quantity of father involvement was associated with higher levels of internalizing and externalizing behavior problems. The positive association between the quantity of father involvement and behavior problems was stronger in adolescents who were physically abused by their father. The association between father involvement and behavior problems did not differ by the type of father co-residing in the home. The findings suggest that policies and interventions aimed at improving the quality of fathers’ relationships and involvement with their children may be helpful in reducing behavior problems in adolescents at risk of maltreatment.  相似文献

Background and Objectives: Preferential attention to threat, emotional response inhibition, and attentional control each purportedly play a key role in anxiety disorders. Divergent psychometric properties among attention measures may produce differential detection of anxiety-related associations and treatment-related changes. However, no studies have directly compared the psychometric properties of these attention measures in the same sample.

Design: Eighty-five young adults (M?=?19.41 years, SD?=?1.47, 48 Females) completed a cognitive task battery and a subset of 60 participants (M?=?19.42 years, SD?=?1.48, 33 Females) completed the task battery again approximately two weeks later.

Method: To assess preferential attention to threat, emotional response inhibition, and attentional control, the cognitive task battery included a dot-probe task, emotion and gender Stroop tasks, and a flanker task. Tasks varied in how attention was directed and if emotional stimuli were included. Internal consistency and test-retest reliability were compared across measures.

Results: Within the same sample, internal consistency and reliability differed across attention measures. Explicit attention measures (emotional Stroop and flanker) exhibited stronger internal consistency and greater test-retest reliability compared to implicit measures (dot-probe and gender Stroop).

Conclusions: These results inform clinical research using attention measures to assess anxiety-related differences and treatment response.  相似文献

Although research has demonstrated a relationship between maternal depression and child attention deficit/hyperactivity disorder (ADHD); the strength of the relationship is currently unclear. The results of some studies have found a strong association between maternal depression and child ADHD, while other studies have found little or no association. A meta-analysis was conducted to clarify the strength of the association between maternal depression and child ADHD. The current study included 51 published and unpublished studies that included a quantitative comparison between maternal depression and child ADHD. Mothers of children with ADHD had significantly higher levels of depressive symptoms than mothers of children without ADHD (d?=?0.58; 95% CI [0.43, 0.74]; p?<?.001; k?=?18). The relationship between maternal depressive symptoms and child ADHD symptoms was moderate (r?=?.22; 95% CI [.17, .28]; p?<?.001; k?=?21). 17.11% of mothers of children with ADHD currently met criteria for a depressive disorder (95% CI [11.95, 23.89], p?<?.001, k?=?19). The DSM version used to evaluate child ADHD status was the only moderator that was statistically significant (p?=?.021, k?=?15). Specifically, studies that used the DSM-III or DSM-III-R were associated with larger effect sizes than studies that used the DSM-IV or DSM-IV-TR. The results suggest that clinicians should screen for the possible co-occurrence of maternal depression when working with families of children with ADHD.  相似文献

A rapidly growing number of working professionals, academic communities, and businesses have applied the Enneagram personality system of nine types to enhance psychological growth in their personal and professional lives. However, there are no existing studies that measure the effects of the application of Enneagram training programs to promote ego development. This study examined if ego development took place among individuals enrolled in Enneagram training programs in the Narrative Tradition. Two groups of participants (N?=?122) were assessed using the Washington University Sentence Completion Test (WUSCT) at baseline (pretest) before the training began and then again 18 months later (posttest); one of the groups participated in Enneagram Intensive training programs (n?=?73) and the other group participated in introductory Enneagram trainings (n?=?49). Data revealed an advancement in ego development among some of the participants who received at least 40–50 h of training. The findings suggest that Enneagram Intensive trainings may be beneficial for promoting psychological growth and ego development. Clinical applications and future research directions are discussed.  相似文献

The Vanderbilt Holistic Processing Test for faces (VHPT-F) is the first standard test designed to measure individual differences in holistic processing. The test measures failures of selective attention to face parts through congruency effects, an operational definition of holistic processing. However, this conception of holistic processing has been challenged by the suggestion that it may tap into the same selective attention or cognitive control mechanisms that yield congruency effects in Stroop and Flanker paradigms. Here, we report data from 130 subjects on the VHPT-F, several versions of Stroop and Flanker tasks, as well as fluid IQ. Results suggested a small degree of shared variance in Stroop and Flanker congruency effects, which did not relate to congruency effects on the VHPT-F. Variability on the VHPT-F was also not correlated with Fluid IQ. In sum, we find no evidence that holistic face processing as measured by congruency in the VHPT-F is accounted for by domain-general control mechanisms.  相似文献

Based on the observation that sports teams rely on colored jerseys to define group membership, we examined how grouping by similarity affected observers’ abilities to track a “ball” target passed between 20 colored circle “players” divided into two color “teams” of 10 players each, or five color teams of four players each. Observers were more accurate and exerted less effort (indexed by pupil diameter) when their task was to count the number of times any player gained possession of the ball versus when they had to count only the possessions by a given color team, especially when counting the possessions of one team when players were grouped into fewer teams of more individual members each. Overall, results confirm previous reports of costs for segregating a larger set into smaller subsets and suggest that grouping by similarity facilitates processing at the set level.  相似文献

The beneficial effects of cognitive-behavioral interventions (particularly exposure and response prevention) for OCD are among the most consistent research findings in the mental health literature. Nevertheless, even after an adequate trial, many individuals experience residual symptoms, and others never receive adequate treatment due to limited access. These and other issues have prompted clinicians and researchers to search for ways to improve the conceptual and practical aspects of existing treatment approaches, as well as look for augmentation strategies. In the present article, we review a number of recent developments and new directions in the psychological treatment of OCD, including (a) the application of inhibitory learning approaches to exposure therapy, (b) the development of acceptance-based approaches, (c) involvement of caregivers (partners and parents) in treatment, (d) pharmacological cognitive enhancement of exposure therapy, and (e) the use of technology to disseminate effective treatment. We focus on both the conceptual/scientific and practical aspects of these topics so that clinicians and researchers alike can assess their relative merits and disadvantages.  相似文献
