The role of speech-language pathologists in supporting theory of mind through literacy-based activities.

Purpose: This tutorial discusses the importance of speech-language pathologists (SLPs) supporting individuals with language disorders in their understanding of others' cognitive and affective states (theory of mind, ToM), with a special consideration given to applying these suggestions with individuals who are neurodivergent.

Method: I motivate this tutorial by first reviewing the literature related to ToM and language abilities for various populations of individuals with language difficulties, highlighting the need for explicitly targeting the language-related skills that are thought to underlie ToM for individuals with language disorders. I next present concrete examples of how to support ToM through literacy-based activities.

Fingerspelling and Its Role in Translanguaging.

Fingerspelling is a critical component of many sign languages. This manual representation of orthographic code is one key way in which signers engage in translanguaging, drawing from all of their linguistic and semiotic resources to support communication. Translanguaging in bimodal bilinguals is unique because it involves drawing from languages in different modalities, namely a signed language like American Sign Language and a spoken language like English (or its written form).

Visual-Spatial Perspective-Taking in Spatial Scenes and in American Sign Language.

As spatial languages, sign languages rely on spatial cognitive processes that are not involved for spoken languages. Interlocutors have different visual perspectives of the signer's hands requiring a mental transformation for successful communication about spatial scenes. It is unknown whether visual-spatial perspective-taking (VSPT) or mental rotation (MR) abilities support signers' comprehension of perspective-dependent American Sign Language (ASL) structures.

Social Abilities and Visual-Spatial Perspective-Taking Skill: Deaf Signers and Hearing Nonsigners.

Social abilities relate to performance on visual-spatial perspective-taking (VSPT) tasks for hearing nonsigners but may relate differently to VSPT abilities for deaf signers because of their distinct linguistic and social experiences. This research investigated whether deaf adults approach VSPT tasks nonsocially (as previously suggested for deaf children) or socially (as seen for hearing adults). Adult hearing nonsigners (n = 45) and deaf signers (n = 44) performed a nonlinguistic VSPT task, mental rotation and spatial orientation tasks, and completed a questionnaire measuring social abilities and degree of socialness.

Assessing the Comprehension of Spatial Perspectives in ASL Classifier Constructions.

In ASL spatial classifier expressions, the location of the hands in signing space depicts the relative position of described objects. When objects are physically present, the arrangement of the hands maps to the observed position of objects in the world (Shared Space). For non-present objects, interlocutors must perform a mental transformation to take the signer's perspective ("Signer Space").

The Action-Sentence Compatibility Effect in ASL: the role of semantics vs. perception.

Embodied theories of cognition propose that humans use sensorimotor systems in processing language. The Action-Sentence Compatibility Effect (ACE) refers to the finding that motor responses are facilitated after comprehending sentences that imply movement in the same direction. In sign languages there is a potential conflict between sensorimotor systems and linguistic semantics: movement away from the signer is perceived as motion toward the comprehender.

Syringeal specialization of frequency control during song production in the Bengalese finch (Lonchura striata domestica).

Background: Singing in songbirds is a complex, learned behavior which shares many parallels with human speech. The avian vocal organ (syrinx) has two potential sound sources, and each sound generator is under unilateral, ipsilateral neural control. Different songbird species vary in their use of bilateral or unilateral phonation (lateralized sound production) and rapid switching between left and right sound generation (interhemispheric switching of motor control).
