Mirror Self‐Recognition and Self‐Identification

That great apes are the only primates to recognise their reflections is often taken to show that they are self‐aware—however, there has been much recent debate about whether the self‐awareness in question is psychological or bodily self‐awareness. This paper argues that whilst self‐recognition does not require psychological self‐awareness, to claim that it requires only bodily self‐awareness would leave something out. That is that self‐recognition requires ‘objective self‐awareness’—the capacity for first person thoughts like ‘that's me’, which involve self‐identification and so are vulnerable to error through misidentification. This objective self‐awareness is distinct from bodily or psychological self‐awareness, requires cognitive sophistication and provides the beginnings of a more conceptual self‐representation which might play a role in planning, mental time travel and theory of mind.     

Maintaining global coherence in reading: The role of sentence boundaries

In four experiments, we examined the reinstatement of backgrounded information in locally coherent passages, investigating the influence of syntactic boundaries, such as periods, on the time course of this process. In Experiment 1, using a line-by-line reading paradigm, readers were delayed in noticing a contradiction on a target line when the sentence continued onto a posttarget line. Consistent with this, in Experiments 2A and 2B, the results of a recognition probe demonstrated that relevant concepts from long-term memory were not integrated immediately unless the contradiction was followed by a period. Experiment 3 demonstrated that sentence boundaries are sufficient to facilitate the integration of related background information but are not necessary; additional time served the same purpose. Consistent with a memory-based text-processing framework, it appears that the reactivation of related information is initiated automatically but that an integration stage is influenced by such factors as syntactic boundaries.     

Perceptions of Overprotection in III Adults1

Several studies have suggested that chronically ill adults who receive overprotective care are more depressed and less motivated in rehabilitation therapy. However, for this area of research to proceed, a standard definition and measurement of perceptions of overprotection are needed. In the present study, long and short forms of a scale (the OPSA) to assess perceptions of being overprotected in chronically ill adults were developed. The scale's psychometric properties were tested with a sample of 161 community-dwelling older adults. It was found to have good internal reliability, to correlate highly with an established retrospective measure of overprotection in adults, and to be distinct from ratings of quantity and quality of social support. As expected, overprotection was associated with poorer adjustment: Respondents who felt overprotected were more depressed.     

Belief in COVID-19 misinformation: Hopeful claims are rated as truer

Misinformation surrounding COVID-19 spread rapidly and widely, posing a significant threat to public health. Here, we examined whether some types of misinformation are more believable than others, to the extent that they offer people hope in uncertain times. An initial group of subjects rated a series of COVID-19 misinformation statements for whether each made them feel more or less hopeful (if true). Based on these ratings, we selected two sets of misinformation that differed in their average rated hopefulness; the two sets did not differ in word length or reading ease. In two studies, people rated their belief in each statement. Results from both studies revealed that people rated the more hopeful misinformation (e.g., COVID cures and prevention methods) as truer than less hopeful misinformation (e.g., transmission vectors). These findings are consistent with a motivated reasoning account of misinformation acceptance.     

Analysis of four measures of positional bias within a multiple stimulus without replacement preference assessment

Positional bias is a pattern of responding to a specific location that can be influenced by response effort and/or prior learning history. Prior research on positional bias within stimulus preference assessments have focused primarily on its use in paired stimulus assessments due to the complex nature of the multiple stimulus without replacement (MSWO) preference assessment. The present study is a secondary data analysis that utilized four different methods to measure side and center bias in a MSWO preference assessment for 19 young children with autism spectrum disorder. Participants displayed varying degrees of biased responding but collectively engaged in minimal biased responding. This study includes an analysis of the four methodologies, discussion of general patterns of responding, and general recommendations for the application of these methodologies in future research.

Ecological Design-Based Research for Computer Science Education: Affordances and Effectivities for Elementary School Students

Abstract

This article integrates an ecological approach and design-based research in computer science education research by following the simultaneous development of a computer programming environment and curriculum for elementary school age children over 2-1/2 years. We studied the alignment of the affordances provided by the programming environment and curriculum with the effectivities of students in 4th through 6th grade (9-12 years old). We used the computer science concept of initializing as a tracer idea and both qualitative and quantitative data to identify mismatches between the affordances provided by our programming environment and the learners’ effectivities. These included requisite mathematical skills, confusion between resetting and setting up, and incorrectly assuming that features of the programming environment conveyed information. We then describe how we addressed the mismatches by removing or adding functionality to the programming environment, adding signifiers, adapting the curriculum to include scaffolding related to the effectivities, or removing activities.     

Cross-modal information integration in category learning

An influential theoretical perspective describes an implicit category-learning system that associates regions of perceptual space with response outputs by integrating information preattentionally and predecisionally across multiple stimulus dimensions. In this study, we tested whether this kind of implicit, information-integration category learning is possible across stimulus dimensions lying in different sensory modalities. Humans learned categories composed of conjoint visual–auditory category exemplars comprising a visual component (rectangles varying in the density of contained lit pixels) and an auditory component (in Exp. 1, auditory sequences varying in duration; in Exp. 2, pure tones varying in pitch). The categories had either a one-dimensional, rule-based solution or a two-dimensional, information-integration solution. Humans could solve the information-integration category tasks by integrating information across two stimulus modalities. The results demonstrated an important cross-modal form of sensory integration in the service of category learning, and they advance the field’s knowledge about the sensory organization of systems for categorization.
