Twofold advantages of face processing with or without visual awareness.

J Exp Psychol Hum Percept Perform 2021 May 13. Epub 2021 May 13.

Key Laboratory of Brain, Cognition and Education Sciences.

The advantages of face processing over processing items in other object categories have been found in conditions both with and without visual awareness. This study examined the possible mechanisms underlying the advantages of processing visible and invisible faces. Specifically, contributions from face-like configurations and face-specific local attributes were evaluated by comparing perceptual processes of three image types: genuine faces, face-like objects, and non-face-like objects.

Irrelevant features of distractors in intervening visual search tasks cause active visual working memory interference - the more difficult the search task, the more interference it causes.

Atten Percept Psychophys 2021 May 11. Epub 2021 May 11.

Department of Psychology, University of Illinois at Urbana-Champaign, Champaign, IL, 61820, USA.

Visual working memory (VWM) content disrupts visual search performance when there is a singleton in the search array that is similar to the content in VWM, even when this singleton is task irrelevant. Typically, the memory-similar singleton captures attention, which results in slower search performance for memory-similar conditions compared to conditions where memory-similar content is absent. Recently, it has also been shown that VWM content may be affected when memory-similar stimuli are processed. Read More

Associations between visual hallucinations and impaired visuo-spatial abilities in dementia with Lewy bodies.

Neuropsychology 2021 Mar;35(3):276-284

Cognitive Neurology Unit, Neurological Institute, Tel Aviv Medical Center.

In dementia with Lewy bodies (DLB) recurrent visual hallucinations (VH) often coexist or occur consecutively to impaired visual perception. Since in-depth neuropsychological testing is time-consuming, and therefore, not routinely performed in clinical settings, we aimed to explore whether standard cognitive screening tests may be helpful to alert a clinician to the presence of VH in DLB by exploring association between visuo-spatial dysfunction and VH. The clock drawing, cube, and pentagons copying items from Montreal Cognitive Assessment and Mini-Mental State Exam and nonmotor Hooper visual organization test (HVOT) have been scored in DLB patients with and without VH using traditional and extended scoring methods.

Multisensory visuo-tactile context learning enhances the guidance of unisensory visual search.

Sci Rep 2021 May 3;11(1):9439. Epub 2021 May 3.

Allgemeine Und Experimentelle Psychologie, Department Psychologie, Ludwig-Maximilians-Universität München, Leopoldstr. 13, 80802, München, Germany.

Does multisensory distractor-target context learning enhance visual search over and above unisensory learning? To address this, we had participants perform a visual search task under both uni- and multisensory conditions. Search arrays consisted of one Gabor target that differed from three homogeneous distractors in orientation; participants had to discriminate the target's orientation. In the multisensory session, additional tactile (vibration-pattern) stimulation was delivered to two fingers of each hand, with the odd-one-out tactile target and the distractors co-located with the corresponding visual items in half the trials; the other half presented the visual array only.

Center for Brain and Mental Well-being, Department of Psychology, Sun Yat-sen University, Guangzhou, China; Peng Cheng Laboratory, Shenzhen, China; Shanghai Key Laboratory of Brain Functional Genomics, Shanghai Changning-ECNU Mental Health Center, School of Psychology and Cognitive Science, East China Normal University, Shanghai, China; NYU-ECNU Institute of Brain and Cognitive Science, NYU Shanghai and Collaborative Innovation Center for Brain Science, Shanghai, China. Electronic address:

We investigated visual working memory (VWM) with a whole-report task, where participants were asked to sequentially recall all the items in an order either chosen by themselves (free recall) or randomly chosen by the computer (forced recall). Comparisons between free and forced recalls helped us understand important but largely neglected aspects of VWM, such as inhomogeneity (different levels of precision) and between-item interference. One unique part of our task was the introduction of a separate item-selection stage before each recall, during which participants located the next item to recall. Read More

Core knowledge of geometry can develop independently of visual experience.

Cognition 2021 Apr 23;212:104716. Epub 2021 Apr 23.

Department of Medical Neurobiology, Hebrew University of Jerusalem, Hadassah Ein-Kerem, Jerusalem, Israel; The Baruch Ivcher Institute For Brain, Cognition & Technology, The Baruch Ivcher School of Psychology, Interdisciplinary Center (IDC), Herzeliya, Israel; The Cognitive Science Program, The Hebrew University of Jerusalem, Jerusalem, Israel.

Geometrical intuitions spontaneously drive visuo-spatial reasoning in human adults, children and animals. Is their emergence intrinsically linked to visual experience, or does it reflect a core property of cognition shared across sensory modalities? To address this question, we tested the sensitivity of blind-from-birth adults to geometrical-invariants using a haptic deviant-figure detection task. Blind participants spontaneously used many geometric concepts such as parallelism, right angles and geometrical shapes to detect intruders in haptic displays, but experienced difficulties with symmetry and complex spatial transformations.
