ABSTRACTPerceived heaviness is a function of both the muscle activity used to wield an object and the resulting movement. Wielding reveals invariant properties of the effector-object system, such as rotational inertia. Recent research has proposed a psychophysiological mechanism for perceiving the heaviness of a handheld object through dynamic touch that captures how arm muscle activity and angular movement combined reveal this invariance (Waddell, Fine, Likens, Amazeen & Amazeen, 2016). The current study extends this hypothesis by investigating the dynamics of heaviness perception with the leg. Participants lifted objects of varying mass with knee extension lifts while reporting perceived heaviness. During each lift, the electromyogram (EMG) was recorded from the quadriceps, and peak angular acceleration was recorded about the knee. The resulting psychophysiological function revealed the hypothesized ratio of muscle activity to movement, similar to that found in Waddell et al. (2016). This suggests that the dynamics for heaviness perception in the leg is similar to that shown in the arm in previous work. 相似文献

The purpose of this study is to test the hypothesis that during audiovisual message processing (e.g., television or film), cuts in the video track cause an orienting response, which is reflected in the involuntary shift of attention. In classic research by Reeves et al. (1985), changes in the alpha band were noticed in reaction to montage cuts. We propose an investigation of the brain's reaction to montage cuts by means of event-related potentials (ERPs), which are the brain's electrophysiological responses to a stimulus. Well-known indices of orienting response are two ERP components: P3 and slow cortical potential (SCP). Ten participants watched a film consisting of 105 related and 114 unrelated cuts while an electroencephalographic signal was recorded. The hypothesis that unrelated cuts in the video track when watching an audiovisual message cause more pronounced SCP was confirmed. There was no effect of unrelated cuts on P3. The results of this study provide a good starting point for further research on brain reactions to the structural features of an audiovisual message, such as close ups or camera moves. 相似文献

ABSTRACTThe authors answer recent responses by Steensma & Cohen-Kettenis (2018) and Zucker (2018) to our critical commentary on “desistance” stereotypes and their underlying research on trans and gender diverse children (Temple Newhook et al., 2018). We provide clarification in the following areas: (1) the scope of our paper; (2) our support of longitudinal studies; (3) consequences of harm to trans and gender diverse children; (4) clinical practice implications; (5) concerns about validity of research methodology; and (6) the importance of learning to listen to trans and gender diverse children. 相似文献

Although a distinction between moral-personal and moral-impersonal dilemmas (Greene, Sommerville, Nystrom, Darley, & Cohen, 2001) has been widely accepted as an explanation for a difference between the trolley and footbridge dilemmas (Thomson, 1985), its psychometric properties remain a mystery. In this study 219 participants completed 62 moral dilemma tasks used in Greene et al. (2001), and the correlation structure among the dilemmas was analysed through factor analysis and structural equation modelling. Findings suggest that, first, moral-personal dilemmas are composed of one factor, indicating that the assumption in Greene et al. (2001) was supported. Second, moral-impersonal dilemmas are explained by two factors that reflect procedural and consequential aspects of decision making. Third, the trolley and footbridge dilemmas fall under the same factor category; therefore the difference between the two dilemmas cannot be attributed to emotional involvement. Additionally, the results of the structural equation modelling suggest that they differ in the engagement of rational processing. 相似文献

The role of categorization in visual search was studied in 3 colour search experiments where the target was or was not linearly separable from the distractors. The linear separability effect refers to the difficulty of searching for a target that falls between the distractors in CIE colour space (Bauer, Jolicoeur, & Cowan, 1996b). Observers performed nonlinearly separable searches where the target fell between the two types of distractors in CIE colour space. When the target and distractors fell within the same category, search was difficult. When they fell within three distinct categories, response times and search slopes were significantly reduced. The results suggest that categorical information, when available, facilitates search, reducing the linear separability effect. 相似文献

A number of factors could explain the adverse effect that babble noise has on memory for spoken words (Murphy, Craik, Li, & Schneider, 2000). Babble could degrade the perceptual representation of words to such an extent that it compromises their subsequent processing, or the presence of speech noise in the period between word presentations could interfere with rehearsal. Thirdly, the top-down processes needed to extract the words from the babble could draw on resources that otherwise would be used for encoding. We tested all these hypotheses by presenting babble either only during word presentation or rehearsal, or by gating the babble on and off 500 ms before and after each word pair. Only the last condition led to a decline in memory. We propose that this decline in memory occurred because participants were focusing their attention on the auditory stream (to enable them to better segregate the words from the noise background) rather than on remembering the words they had heard. To further support our claim we show that a similar memory deficit results when participants perform the same memory task in quiet together with a nonauditory attention-demanding secondary task. 相似文献

The authors investigated how the relationship between the acts of proactive and reactive aggression was moderated by the individual differences in cognitive regulation of emotion. An aggression paradigm, a electrocardiogram recording, a cognitive assessment battery, and a short form IQ test were completed by 109 children, aged 8 to 13 years (Juujärvi, Kaartinen, Laitinen, Vanninen, & Pulkkinen, 2006; Juujärvi, Kooistra, Kaartinen, & Pulkkinen, 2001; Lehto, Juujärvi, Kooistra, & Pulkkinen, 2003). The less the children subdued the intensity of their defence to the attacks in the aggression paradigm, the poorer they performed in the cognitive assessment battery tasks measuring Working memory capacity and in the task assessing crystallised intelligence. The mean cardiovascular reactivity during the aggression paradigm was neither associated with the performances in either the cognitive assessment battery nor the intelligence tasks. Both information processing and knowledge dimensions of cognition contributed to regulation of emotion, but the respective effects of the processes cannot be inferred from the mean cardiovascular reactivity. 相似文献

Anhedonia—the reduced capacity to experience pleasure—is a trait implicated in mental and physical health. Yet, psychometric data on anhedonia measures in adolescents are absent. We conducted an in-depth psychometric analysis of the Snaith–Hamilton Pleasure Scale (SHAPS; Snaith et al., 1995)—a self-report measure of anticipated pleasure response to 14 pleasant experiences—in adolescents. Adolescents (N = 585, M age = 14.5) completed the SHAPS and other paper-and-pencil surveys. Item response theory models were used to evaluate the psychometric performance of each SHAPS item. Correlations of the SHAPS with other personality and psychopathology measures were calculated to evaluate construct validity. Results showed that (a) certain items (e.g., reported pleasure from basic experiences like “seeing smiling faces” or “smelling flowers”) provided more information about latent anhedonia than others; and (b) SHAPS scales exhibited construct-consistent convergent and discriminant validity (i.e., stronger correlations with low positive affect constructs, weaker correlations with negative affect). Reporting diminished pleasure from basic pleasant experiences accurately indicates adolescent anhedonia, which is important for future scale development and understanding the phenomenology of anhedonia in teens. These data support using the SHAPS for assessing anhedonia in epidemiological research and school-based universal prevention programming in general adolescent populations. 相似文献

There are currently two computational accounts of how the time to read pseudohomophones (like BRANE) and their nonword controls (like FRANE) varies with changes in context. In Reynolds and Besner's (2005) account, readers vary the breadth of lexical activation in response to changes in context. A competing account proposed by Kwantes and Marmurek (2007) and independently by Perry, Ziegler, and Zorzi (2007) has readers varying their response criterion in response to changes in context. The present work adjudicates between these two accounts by examining how the effect of neighbourhood density changes as a function of list context when reading pseudohomophones aloud. The results of an experiment and simulations from a leading computational model support the lexical breadth account, but are inconsistent with the response criterion account. 相似文献

Hoijtink, Kooten, and Hulsker (2016) present a method for choosing the prior distribution for an analysis with Bayes factor that is based on controlling error rates, which they advocate as an alternative to our more subjective methods (Morey &; Rouder, 2014; Rouder, Speckman, Sun, Morey, &; Iverson, 2009; Wagenmakers, Wetzels, Borsboom, &; van der Maas, 2011). We show that the method they advocate amounts to a simple significance test, and that the resulting Bayes factors are not interpretable. Additionally, their method fails in common circumstances, and has the potential to yield arbitrarily high Type II error rates. After critiquing their method, we outline the position on subjectivity that underlies our advocacy of Bayes factors. 相似文献

Watson (2005) proposed a hierarchical reorganization of the underlying structure of emotional disorders. This study cross-culturally evaluated Watson's (2005) structure of mood and anxiety disorders, using mainly dichotomous criteria, and explored the placement of obsessive–compulsive disorder (OCD) in this model. It also tested Sellbom, Ben-Porath, and Bagby's (2008) proposed elaboration of the 2-factor model (positive and negative activation) that incorporates a higher order dimension of demoralization. One hundred men and 133 women from psychiatric settings in Israel completed the Minnesota Multiphasic Personality Inventory–2 (Butcher et al., 2001) and the Maudsley Obsessional–Compulsive Inventory (Hodgson &; Rachman, 1977). They were interviewed using the Mini International Neuropsychiatric Interview (Sheehan et al., 1998). Confirmatory factor analyses replicated Watson's structure for women but not for men. Mixed results were obtained regarding OCD's location in the model. Findings among women support the applicability of Watson's (2005) model across a variety of assessment modalities, as well as in a different language and for diversified cultural backgrounds. This conclusion, however, should be tempered in consideration of the results among men. Findings also provide evidence of the importance of demoralization in mood and anxiety disorders. 相似文献

Theory of mind (ToM) is commonly measured in young children by the false belief task. Many researchers claim that 3-year-olds' failure on false belief tasks is due to task constraints. Experiment 1 empirically tested the claim made by Wellman, Cross, and Watson (2001), that even when variables that enhance performance on the false belief task (deception; participation in transformation; salience; and item not real and present) are included in one task, 3-year-olds will still fail to perform above chance level. On the standard task 4-year-olds did perform significantly better than 3-year-olds, although there was no significant difference on the adapted task. Compared to the standard task, 3-year-olds performed better on the adapted task, although this improvement was not significant and performance was still not above chance level. Experiment 2 examined the influence of two additional variables; presence of protagonist at the time when the false belief question is asked, and the order in which test questions are asked (memory preceding false belief or vice versa). Results found no significant effects of either presence of the protagonist or question order on the performance of participants. Results are discussed with reference to reasons behind the failure of some children on false belief tasks. 相似文献

Hockley, Hemsworth, and Consoli (1999) found that following the study of normal faces, a recognition test of normal faces versus faces wearing sunglasses produced a mirror effect: The sunglasses manipulation decreased hit rates and increased false-alarm rates. The stimuli used by Hockley et al. (1999) consisted of separate poses of models wearing or not wearing sunglasses. In the current experiments, we separately manipulated same versus different depictions of individual faces and whether or not the faces were partially obscured. The results of a simulation and four experiments suggest that the test-based, mirror effect observed by Hockley et al. (1999) is actually two separable effects. 相似文献

Much research has been directed at the validity of fit indices in Path Analysis and Structural Equation Modeling (e.g., Browne, MacCallum, Kim, Andersen, &; Glaser, 2002; Heene, Hilbert, Draxler, Ziegler, &; Bühner, 2011; Hu &; Bentler, 1999; Marsh, Hau, &; Wen, 2004). Recent developments (e.g., Preacher, 2006; Roberts &; Pashler, 2000, 2002) have encouraged researchers to investigate other criteria for comparing models, including model complexity. What has not been investigated is the inherent ability of a particular data set to be fitted with a constrained set of randomly generated linear models, which we call Model Conditioned Data Elasticity (DE). In this article we show how DE can be compared with the problem of equivalent models and a more general problem of the “confoundability” of data/model combinations (see MacCallum, Wegener, Uchino, &; Fabrigar, 1993). Using the DE package in R, we show how DE can be assessed through automated computer searches. Finally, we discuss how DE fits within the controversy surrounding the use of fit statistics. 相似文献

Previous research suggests that there are significant differences in the operation of reference memory for stimuli of different modalities, with visual temporal entries appearing to be more durable than auditory entries (Ogden, Wearden, & Jones, 2008, 2010). Ogden et al. (2008, 2010) demonstrated that when participants were required to store multiple auditory temporal standards over a period of delay there was significant systematic interference to the representation of the standard characterized by shifts in the location of peak responding. No such performance deterioration was observed when multiple visually presented durations were encoded and maintained. The current article explored whether this apparent modality-based difference in reference memory operation is unique to temporal stimuli or whether similar characteristics are also apparent when nontemporal stimuli are encoded and maintained. The modified temporal generalization method developed in Ogden et al. (2008) was employed; however, standards and comparisons varied by pitch (auditory) and physical line length (visual) rather than duration. Pitch and line length generalization results indicated that increasing memory load led to more variable responding and reduced recognition of the standard; however, there was no systematic shift in the location of peak responding. Comparison of the results of this study with those of Ogden et al. (2008, 2010) suggests that although performance deterioration as a consequence of increases in memory load is common to auditory temporal and nontemporal stimuli and visual nontemporal stimuli, systematic interference is unique to auditory temporal processing. 相似文献

ABSTRACTRelationship self-regulation refers to the “work” partners put in to keep their relationships healthy. Past relationship self-regulation research has not taken into account distal variables that may affect it, such as respondents’ own and parental avoidant couple conflict-resolution styles. Using data from 4,456 people in their first marriages who completed the RELATionship Evaluation (RELATE) (Busby, Holman, & Taniguchi, 2001), the current study found a positive correlation between parents’ couple avoidant conflict-resolution style and respondents’ avoidant couple conflict-resolution style. Respondents’ avoidant couple conflict-resolution style was also negatively correlated with relationship self-regulation. Perception of partners’ secure attachment behaviors, however, had a significant strong relationship with respondents’ ability to do relationship self-regulation. 相似文献

Keysar et al. (Keysar, Barr, Balin, & Brauner, 2000; Keysar, Lin, & Barr, 2003) report that adults frequently failed to use their conceptual competence for theory of mind (ToM) in an online communication game where they needed to take account of a speaker's perspective. The current research reports 3 experiments investigating the cognitive processes contributing to adults' errors. In Experiments 1 and 2 the frequency of adults' failure to use ToM was unaffected by perspective switching. In Experiment 3 adults made more errors when interpreting instructions according to the speaker's perspective than according to an arbitrary rule. We suggest that adults are efficient at switching perspectives, but that actually using what another person knows to interpret what they say is relatively inefficient, giving rise to egocentric errors during communication. 相似文献
