Título: Hand movements reveal the time course of gender stereotypes during facial categorization
Autor: Gutiérrez- Blanco, Francisco; Palenciano, Ana F.; Ruz, María
Resumen: Our prior knowledge of what is about to occur, or perceptual expectations, influences how we perceive and interpret information, including the social context. The general objective of the present investigation was to replicate and extend the research conducted by Barnett et al. (2021) studying how gender stereotype-based expectations modulate the perception and categorization of faces, by employing a mouse tracking technique. To achieve this, mouse movements were continuously recorded during the categorization of the gender and emotion of a series of photos that were either congruent (angry male and happy female) or incongruent (happy male and angry female) with gender stereotypes. Analyses of the mouse trajectories revealed sustained cognitive conflict while categorizing incongruent faces. In addition, Representational Similarity Analysis (RSA) applied to the dynamics of mouse trajectories indicated that the impact of stereotypes fluctuated across time, being modulated by stereotypes during the end points of movements. Overall, our results replicate and extend previous studies and highlight the advantages of using continuous behavioral recording techniques, in particular mouse tracking, to analyze not only the influence, but also the temporal impact of expectations on social perception and categorization.2024-03-12T14:59:42ZDevelopment and Validation of the Interoceptive Attribution of Physical Effort Scale (IAPES)

Resumen: Interoception is the perception of internal bodily signals, including those related to physical effort. Common approaches to measuring interoception include monitoring perceived heartbeats, breathing, gastric activity, and emotions, often through self-reports questionnaires. However, there has been no study of how people use interoception to interpret physical effort experienced during physical activities. Thus, in this study, we aimed to develop and validate a self-report scale to determine an individual’s interoceptive attributions to physical effort. We conducted content, construct, and criterion validity tests on a new measure, the Interoceptive Attribution of Physical Effort Scale (IAPES) and found it to have good content (≥ 0.7), construct (≥ 0.9), and criterion validity (Odds Ratio ≥ 1.3). The IAPES provided relevant information on interoceptive attribution to physical effort, and it can now be used to aid exercise prescription and monitoring.2024-02-26T10:50:49ZAgency matters for sensory attenuation in multi-step actions

Título: Agency matters for sensory attenuation in multi-step actions
Autor: Garrido-Vásquez, Patricia
Resumen: The Sense of Agency (SoA) refers to the sense of controlling our actions and, by that, events in the outside world. A common SoA measure is sensory attenuation, the phenomenon that self-produced action effects are perceived as less intense than physically identical but externally produced effects. However, some recent studies cast doubt on the validity of sensory attenuation as a cue to the SoA and raise the possibility that sensory attenuation is a product of enhanced stimulus predictability rather than a correlate of the SoA per se. The present study aimed to further investigate the validity of sensory attenuation as a measure of the SoA within a multi-step action paradigm. Participants (N = 40) produced tones with a button press during one block and with a sequence of three button presses in another. The timings in these blocks were recorded and subsequently replayed, and button presses were replaced by numbers on the screen, which in the 3-step condition rendered the tones highly predictable despite the absence of an action. By means of a psychophysical task, sensory attenuation of the tones was measured through the point of subjective equality (PSE). The results revealed stronger sensory attenuation for self-generated than externally generated tones, irrespective of the number of steps. Judgments of agency, measured only in the active conditions, were higher for tones produced with the 1-step than the 3-step action. The results underline the importance of motor action for sensory attenuation and point to reduced agency perception in multi-step actions.2024-02-14T17:58:31ZDifferentiating expectancy: Impacts of item-related and source-related expectancy on episodic memory

Título: Differentiating expectancy: Impacts of item-related and source-related expectancy on episodic memory
Autor: Nie, Aiqing; Xiao, Yueyue
Resumen: The relationship between expectancy and episodic memory has received significant attention in recent decades. Research has consistently discovered either a congruency effect, where expected stimuli are better memorized than unexpected ones, or a reversed pattern. However, no effort has been made towards classifying different types of expectancy yet. In the current study, two experiments were conducted to investigate separately how item-related expectancy (Experiment 1) and source-related expectancy (Experiment 2) would influence item memory and source memory. The expectancy was elicited through the experimentally established schemas, and stimulus emotionality was taken into consideration. The data indicated that: (a) the congruency effect mainly occurred in the item-related expectancy case, supporting the view of fast-pass and elaborate encoding for the expected information; (b) the absence of an item-related expectancy effect in positive words suggested the superiority of processing positive information. (c) the impact of expectancy on memory could be modulated by the stimulus emotionality, depending on the circumstances. Accordingly, various accounts and suggestions for future directions are offered.2024-01-07T18:29:18Z
