This paper presents a usage-based cognitive approach to the different rates at which Icelandic masculine forms in nominative/accusative plural -ur are reanalysed as feminine. Of the 14.92% of nouns in plural -ur, 91.89% are feminine, others masculine. Syncretism in nominative/accusative plural is exceptionless among feminines, but relatively rare among masculines. Interestingly, plurals such as masculine eigendur ‘owners’, fætur ‘feet’, vetur ‘winters’ occasionally yield the feminine outputs definite eigendur-nar, fætur-nar, vetur-nar, and are sometimes modified by feminine forms of adjectives and determiners. As the full set of forms in plural -ur is highly schematic, we might expect reanalysis – viewed as a property of a schema’s productivity – to correlate proportionately with the frequency of corresponding masculine forms. However, corpus data for Icelandic betray a mismatch. Through a network model approach that emphasises prototype structure, minimal schematicity is shown to impact the rate of reanalysis by means of a gang effect.

Two parallel processes structure American politics in the current moment: partisan polarization and the increasing linkage between racial attitudes and issue preferences of all sorts. We develop a novel theory that roots these two trends in historical changes in party coalitions. Changing racial compositions of the two major parties led to the formation of racialized images about Democrats and Republicans in people’s minds—and these images now structure Americans’ partisan loyalties and policy preferences. We test this theory in three empirical studies. First, using the American National Election Studies we trace the growing racial gap in party coalitions as well as the increasing overlap between racial and partisan affect. Then, in two original survey studies we directly measure race–party schemas and explore their political consequences. We demonstrate that race–party schemas are linked to partisan affect and issue preferences—with clear implications for the recent developments in U.S. politics.

Background: Schema Theory proposes that the development of maladaptive schemas are based on a combination of memories, emotions and cognitions regarding oneself and one's relationship to others. A cognitive model of psychosis suggests that schemas are crucial to the development and persistence of psychosis. Little is known about the impact that schemas may have on those considered to be at clinical high risk (CHR) of developing psychosis. Aims: To investigate schemas over time in a large sample of CHR individuals and healthy controls. Method: Sample included 765 CHR participants and 280 healthy controls. Schemas were assessed at baseline, 6 and 12 months using the Brief Core Schema Scale (BCSS). Baseline schemas were compared to 2-year clinical outcome. Results: CHR participants evidenced stable and more maladaptive schemas over time compared to controls. Schemas at initial contact did not vary amongst the different clinical outcome groups at 2 years although all CHR outcome groups evidenced significantly worse schemas than healthy controls. Although there were no differences on baseline schemas between those who later transitioned to psychosis compared to those who did not, those who transitioned to psychosis had more maladaptive negative self-schemas at the time of transition. Associations between negative schemas were positively correlated with earlier abuse and bullying. Conclusions: These findings demonstrate a need for interventions that aim to improve maladaptive schemas among the CHR population. Therapies targeting self-esteem, as well as schema therapy may be important work for future studies.

Self-help cognitive behaviour therapy has been found helpful in treating anxiety and depression. Recent evidence suggests that self-help schema therapy may represent another treatment alternative. The present study aimed to provide a preliminary assessment of the efficacy of self-help schema therapy on psychological distress and early maladaptive schemas (EMSs) using a 6-week treatment protocol with minimal email contact. Method: Participants were recruited from the general population and randomly assigned to self-help schema therapy (n = 32) or a waitlist (n = 32). Intent-to-treat analyses and study completer analyses were conducted using repeated-measures analyses of variance (time × group). Results: Intent-to-treat analyses revealed that treatment produced a marginal improvement in distress, but no change in EMSs. Among study completers (n = 34), self-help schema therapy yielded large reductions in distress scores on the Outcome Questionnaire-45.2 (partial eta squared = .16). Compared to the waitlist, self-help schema therapy also produced a moderate decrease in EMSs (partial eta squared = .10). The majority of study completers showed reliable clinical change in distress and reported high levels of satisfaction with the intervention. Conclusion: Self-help schema therapy may be an effective treatment for those individuals who persist in treatment. Self-help schema therapy has the potential to help a large number of individuals who may not otherwise have access to services. More research is needed to determine variables associated with treatment adherence and successful outcome.

Intermediate constructs are required as bridges between complex behaviors and realistic models of neural circuitry. For cognitive scientists in general, schemas are the appropriate functional units; brain theorists can work with neural layers as units intermediate between structures subserving schemas and small neural circuits.

After an account of different levels of analysis, we describe visuomotor coordination in terms of perceptual schemas and motor schemas. The interest of schemas to cognitive science in general is illustrated with the example of perceptual schemas in high-level vision and motor schemas in the control of dextrous hands.

Rana computatrix, the computational frog, is introduced to show how one constructs an evolving set of model families to mediate flexible cooperation between theory and experiment. Rana computatrix may be able to do for the study of the organizational principles of neural circuitry what Aplysia has done for the study of subcellular mechanisms of learning. Approach, avoidance, and detour behavior in frogs and toads are analyzed in terms of interacting schemas. Facilitation and prey recognition are implemented as tectal-pretectal interactions, with the tectum modeled by an array of tectal columns. We show how layered neural computation enters into models of stereopsis and how depth schemas may involve the interaction of accommodation and binocular cues in anurans.

Historically, the principal function of vision has been to provide the information needed to support action. Visually mediated actions rely on three systems: the gaze system responsible for locating and fixating task-relevant objects, the motor system of the limbs to carry out the task, and the visual system to supply information to the other two. All three systems are under the control of a fourth system, the schema system, which specifies the current task and plans the overall sequence of actions. These four systems have separate but interconnected cortical representations. The way these systems interact in time and space is discussed here in relation to two studies of the gaze changes and manipulations made during two ordinary food preparation tasks. The main conclusions are that complex action sequences consist of a succession of individual object-related actions, each of which typically involve a turn toward the object (if needed), followed by fixation and finally manipulation monitored by vision. Gaze often moves on to the next object just before manipulation is complete. Task-irrelevant objects are hardly ever fixated, implying that the control of fixation comes principally from top-down instructions from the schema system, not bottom-up salience. Single fixations have identifiable functions (locating, directing, guiding, and checking) related to the action to be taken. Several variants of the basic object-related action scheme are discussed, including single-action events in ball sports involving only one anticipatory gaze shift, continuous production loops in text and music reading, and storage–action alternation in copying tasks such as portrait sketching.

The relationship between schemas, depression and psychotic themes was explored in a sample of 26 patients with schizophrenia. Results show an association of underlying depressive schema vulnerabilities with specific psychotic themes. This preliminary investigation provides support for the meaningfulness of psychotic symptoms. This paper implies that schema focused cognitive behavioural therapy (CBT) could lead to improvements in linked psychotic symptoms.
