Conserved Sequence Processing in Primate Frontal Cortex.

An important aspect of animal perception and cognition is learning to recognize relationships between environmental events that predict others in time, a form of relational knowledge that can be assessed using sequence-learning paradigms. Humans are exquisitely sensitive to sequencing relationships, and their combinatorial capacities, most saliently in the domain of language, are unparalleled. Recent comparative research in human and nonhuman primates has obtained behavioral and neuroimaging evidence for evolutionarily conserved substrates involved in sequence processing. The findings carry implications for the origins of domain-general capacities underlying core language functions in humans. Here, we synthesize this research into a 'ventrodorsal gradient' model, where frontal cortex engagement along this axis depends on sequencing complexity, mapping onto the sequencing capacities of different species

Adolescent Writing Instruction: A Return to the Sentence

The ability to write well is inextricably linked to reading comprehension, acquisition of content knowledge, and college and career readiness. Many adolescent students, especially those from economically challenged (EC) households, struggle in their ability to communicate in writing, especially in writing to explain or inform across subject areas. While high school students are expected to produce compositions and research papers, they often need the most support at the single sentence level. The purpose of this qualitative study was to explore the characteristics of students’ writing in a high school serving students from predominantly ED households in a large urban setting, a school that implemented a method of scaffolded and embedded writing instruction across all subject areas. This study was framed by sociocultural theory (Vygotsky, 1978), cognitive load theory (Sweller, 1988), and the capacity theory of writing (McCutchen, 1996). Content analysis of historical student and teacher-created documents was used to examine the characteristics of writing composed by 79 ninth grade students before and after four months of exposure to the Hochman Method sentence-level scaffold, and to explore educators’ perceptions of the impact of the writing instruction on their students’ writing as well as their own practice. An inductive analysis of educator interviews was used to provide context for the student and teacher document analysis. Direct participants included two teachers and one instructional coach. This study extended previous research about embedded grammar instruction and writing across content areas. Limitations included the inability to interview students and time between the phenomenon and educator interviews due to school-based challenges posed by the COVID-19 coronavirus pandemic. Findings highlight the importance of students’ command of the sentence in expository writing and the impact of embedding writing instruction in the content areas. Further research should be done to investigate the impact of embedded, sentence-level writing instruction on the writing of adolescent students, including English Language Learners. Recommendations for educators and policymakers are discussed

Directional adposition use in English, Swedish and Finnish

Directional adpositions such as to the left of describe where a Figure is in relation to a Ground. English and Swedish directional adpositions refer to the location of a Figure in relation to a Ground, whether both are static or in motion. In contrast, the Finnish directional adpositions edellä (in front of) and jäljessä (behind) solely describe the location of a moving Figure in relation to a moving Ground (Nikanne, 2003). When using directional adpositions, a frame of reference must be assumed for interpreting the meaning of directional adpositions. For example, the meaning of to the left of in English can be based on a relative (speaker or listener based) reference frame or an intrinsic (object based) reference frame (Levinson, 1996). When a Figure and a Ground are both in motion, it is possible for a Figure to be described as being behind or in front of the Ground, even if neither have intrinsic features. As shown by Walker (in preparation), there are good reasons to assume that in the latter case a motion based reference frame is involved. This means that if Finnish speakers would use edellä (in front of) and jäljessä (behind) more frequently in situations where both the Figure and Ground are in motion, a difference in reference frame use between Finnish on one hand and English and Swedish on the other could be expected. We asked native English, Swedish and Finnish speakers’ to select adpositions from a language specific list to describe the location of a Figure relative to a Ground when both were shown to be moving on a computer screen. We were interested in any differences between Finnish, English and Swedish speakers. All languages showed a predominant use of directional spatial adpositions referring to the lexical concepts TO THE LEFT OF, TO THE RIGHT OF, ABOVE and BELOW. There were no differences between the languages in directional adpositions use or reference frame use, including reference frame use based on motion. We conclude that despite differences in the grammars of the languages involved, and potential differences in reference frame system use, the three languages investigated encode Figure location in relation to Ground location in a similar way when both are in motion.
