Between Recognition and Mis/Nonrecognition: Strategies of Negotiating and Performing Identities Among White Muslims in the United Kingdom

This article explores white British Muslim experiences of, and strategic performative responses to, the (mis/non)recognition of their seemingly incompatible religious and ethnic identities. Based on in-depth interviews (N = 26), it highlights how the different identity categories they hold relate to one another, influencing processes of perceived recognition in interactional contexts. White British Muslims perceive their ethnic and religious identities to be (mis/not) recognized in complex and contradictory ways. Their identities are affirmed, denied, erased, and/or incorrectly ascribed, sometimes simultaneously, by relevant others in different contexts. Performative strategies such as the adoption, maintenance, or removal of identity markers are used consciously and agentically in attempts to take back control over how their identities are (mis/not) recognized. At times deliberate performative acts leading to misrecognition are orchestrated by white Muslims themselves to not only minimize the risk of experiencing possible harm or marginalization but also to transgress and challenge norms. They also assert their multiple identities as a response to (mis/non)recognition and claims of their identities being incompatible, regardless of the repercussions that may result in them being placed at the margins of, or excluded from, their ingroups.     

No Benefit of Eye-Closure Rehearsal in a Unimodal Recognition Memory Test for Word Items

Recent studies have suggested that closing the eyes helps memory retrieval in recall tests for audiovisual clips that contain multimodal information. In two experiments, we examined whether eye-closure improves recognition memory performance for word lists presented unimodally (i.e., visually or aurally). In the encoding phase, participants saw or heard a list of unrelated, meaningful word items. After a fixed retention interval of 1 week (Experiment 1, n = 110) and 5 min (Experiment 2, n = 44), the participants were asked to mentally rehearse the items with their eyes open or closed, and then they performed a recognition test. The results revealed no effect of eye-closure rehearsal on recognition performance. We discuss the possible reasons why no eye-closure benefit was found in recognition memory tests for unrelated word items.     

Infusion of protein synthesis inhibitors in the entorhinal cortex blocks consolidation but not reconsolidation of object recognition memory

Memory consolidation and reconsolidation require the induction of protein synthesis in some areas of the brain. Here, we show that infusion of the protein synthesis inhibitors anisomycin, emetine and cycloheximide in the entorhinal cortex immediately but not 180 min or 360 min after training in an object recognition learning task hinders long-term memory retention without affecting short-term memory or behavioral performance. Inhibition of protein synthesis in the entorhinal cortex after memory reactivation involving either a combination of familiar and novel objects or two familiar objects does not affect retention. Our data suggest that protein synthesis in the entorhinal cortex is necessary early after training for consolidation of object recognition memory. However, inhibition of protein synthesis in this cortical region after memory retrieval does not seem to affect the stability of the recognition trace.     

Pedestrians at the kerb – Recognising the action intentions of humans

Aim of the presented research is the development of a cognitive driver assistance system, which can capture the traffic situation, analyse it, and warn the driver in case a pedestrian is a potential hazard. Hence parameters have to be identified by which the intention of the pedestrian can be unambiguously predicted. Two approaches to the topic are addressed. First, the pedestrian’s perspective was taken. The question was how crossing decisions were influenced by the parameters distance and velocity of the car. Following a signal, participants had to choose to cross the road in front of or behind the car. The data analysis showed that pedestrians relied on the distance of the car rather than the time to collision for their decision. In the second experiment the observer’s perspective raised the question what parameters humans use to predict pedestrians’ intentions. Videos of natural traffic scenes were presented. Participants had to make statements about whether the shown pedestrian would cross the street during the next moment. In a baseline and four experimental conditions, certain information was masked in the videos. Just the condition in which only the trajectory information of the pedestrian was available produced a higher error rate.     

Recognition of a 3D snake model and its 2D photographic image by captive black tufted-ear marmosets (Callithrix penicillata)

Two-dimensional (2D) displays of real three-dimensional (3D) objects are frequently used experimental tools in animal studies. Whether marmoset monkeys, with their highly diverse and complex anti-predation strategies, readily recognized 2D representations of potential threats has yet to be determined, as seen in other primates. Thus, the behavioral responses of adult captive black tufted-ear marmosets (Callithrix penicillata) toward an unfamiliar motionless snake-model and its photograph were assessed. Pictorially naïve subjects were randomly divided into two groups (n = 12/each) and submitted to two trials. Group 1 was initially exposed to the 3D object and after 1 week to its photograph. Group 2 was first presented the picture and only tested with the real object 1 week later. All 15-min trials were divided into three consecutive 5-min intervals: pre-exposure, exposure and post-exposure. In the presence of the 3D snake object, regardless of its presentation order, the frequency of direct gazes, head-cocks, tsik-tsik alarm/mobbing calls and genital displays increased significantly. The photograph induced a similar response, although only when the object had been previously presented, as significantly higher levels of these behaviors were seen in Group 1 than Group 2. Proximity to the stimulus, aerial scan, terrestrial glance, displacement activities and locomotion were not consistently influenced by the stimuli’s presence and/or order of presentation. Therefore, marmosets recognized and responded appropriately to biologically and emotionally relevant 3D and 2D stimuli. Since the aversive/fearful reactions toward the photograph were only seen after the snake object had been presented, the former seems to be essentially a learned response.     

They do what they are told to do: the influence of instruction on (chess) expert perception-commentary on linhares and brum (2007)

Linhares and Brum (2007) argue that they provide evidence for analogy as the main principle behind experts' acquisition of perceptual knowledge. However, the methodology they used—asking players to pair positions using abstract similarity—raises the possibility that the task reflects more the effect of directional instructions than the principles underlying the acquisition of knowledge. Here we replicate and extend Linhares and Brum's experiment and show that the matching task they used is inadequate for drawing any conclusions about the nature of experts' perception. When expert chess players were instructed to match problems based on similarities at the abstract level (analogy), they produced more abstract pairs than pairs based on concrete similarity. However, the same experts produced more concrete pairs than abstract ones when instructed to match the problems based on concrete similarity. Asking experts to match problems using explicit instructions is not an appropriate way to show the importance of either analogy or similarity in the acquisition of expert knowledge. Experts simply do what they are told to do.     

Dissociating the effects of angular disparity and image similarity in mental rotation and object recognition

Performance is often impaired linearly with increasing angular disparity between two objects in tasks that measure mental rotation or object recognition. But increased angular disparity is often accompanied by changes in the similarity between views of an object, confounding the impact of the two factors in these tasks. We examined separately the effects of angular disparity and image similarity on handedness (to test mental rotation) and identity (to test object recognition) judgments with 3-D novel objects. When similarity was approximately equated, an effect of angular disparity was only found for handedness but not identity judgments. With a fixed angular disparity, performance was better for similar than dissimilar image pairs in both tasks, with a larger effect for identity than handedness judgments. Our results suggest that mental rotation involves mental transformation procedures that depend on angular disparity, but that object recognition is predominately dependent on the similarity of image features.     

Testing the Role of Phonology in Reading: Focus on Sentence Processing

Most reading research investigating the role of phonology in word recognition has focused on studies employing an individual word as the sole stimulus. The bulk of such research has offered support for the phonological recoding hypothesis, the conjecture that access to a printed word’s meaning requires activation of the word’s phonology (i.e., meaning is not typically activated via orthography alone). A criticism of such studies is that by presenting participants with only a single word on each experimental trial (a nonecological manipulation), participants may alter their typical strategy of reading in such a way as to artificially favor the phonological recoding hypothesis. The present study avoided a focus on single words by requiring participants to read sentences and paragraphs for comprehension. Experiment 1 showed that, in reading a paragraph of connected sentences, eliminating a letter in a word that altered the phonology was more deleterious than eliminating a letter that did. Experiment 2 focused on the reading of each sentence itself rather than on the paragraph and provided additional control conditions. The results were similar to those of Experiment 1, consistent with the phonological recoding hypothesis.     

Spoken word recognition by eye

Spoken word recognition is thought to be achieved via competition in the mental lexicon between perceptually similar word forms. A review of the development and initial behavioral validations of computational models of visual spoken word recognition is presented, followed by a report of new empirical evidence. Specifically, a replication and extension of Mattys, Bernstein & Auer's (2002) study was conducted with 20 deaf participants who varied widely in speechreading ability. Participants visually identified isolated spoken words. Accuracy of visual spoken word recognition was influenced by the number of visually similar words in the lexicon and by the frequency of occurrence of the stimulus words. The results are consistent with the common view held within auditory word recognition that this task is accomplished via a process of activation and competition in which frequently occurring units are favored. Finally, future directions for visual spoken word recognition are discussed.
