A systematic review of protocol studies on conceptual design cognition: design as search and exploration

This paper reports findings from the first systematic review of protocol studies focusing specifically on conceptual design cognition, aiming to answer the following research question: What is our current understanding of the cognitive processes involved in conceptual design tasks carried out by individual designers? We reviewed 47 studies on architectural design, engineering design and product design engineering. This paper reports 24 cognitive processes investigated in a subset of 33 studies aligning with two viewpoints on the nature of designing: (V1) design as search (10 processes, 41.7%); and (V2) design as exploration (14 processes, 58.3%). Studies on search focused on solution search and problem structuring, involving: long-term memory retrieval; working memory; operators and reasoning processes. Studies on exploration investigated: co-evolutionary design; visual reasoning; cognitive actions; and unexpected discovery and situated requirements invention. Overall, considerable conceptual and terminological differences were observed among the studies. Nonetheless, a common focus on memory, semantic, associative, visual perceptual and mental imagery processes was observed to an extent. We suggest three challenges for future research to advance the field: (i) developing general models/theories; (ii) testing protocol study findings using objective methods conducive to larger samples and (iii) developing a shared ontology of cognitive processes in design

Towards a shared ontology: a generic classification of cognitive processes in conceptual design

Towards addressing ontological issues in design cognition research, this paper presents the first generic classification of cognitive processes investigated in protocol studies on conceptual design cognition. The classification is based on a systematic review of 47 studies published over the past 30 years. Three viewpoints on the nature of design cognition are outlined (search, exploration and design activities), highlighting considerable differences in the concepts and terminology applied to describe cognition. To provide a more unified view of the cognitive processes fundamentally under study, we map specific descriptions of cognitive processes provided in protocol studies to more generic, established definitions in the cognitive psychology literature. This reveals a set of 6 categories of cognitive process that appear to be commonly studied and are therefore likely to be prevalent in conceptual design: (1) long-term memory; (2) semantic processing; (3) visual perception; (4) mental imagery processing; (5) creative output production and (6) executive functions. The categories and their constituent processes are formalised in the generic classification. The classification provides the basis for a generic, shared ontology of cognitive processes in design that is conceptually and terminologically consistent with the ontology of cognitive psychology and neuroscience. In addition, the work highlights 6 key avenues for future empirical research: (1) the role of episodic and semantic memory; (2) consistent definitions of semantic processes; (3) the role of sketching from alternative theoretical perspectives on perception and mental imagery; (4) the role of working memory; (5) the meaning and nature of synthesis and (6) unidentified cognitive processes implicated in conceptual design elsewhere in the literature

Mistakes in medical ontologies: Where do they come from and how can they be detected?

We present the details of a methodology for quality assurance in large medical terminologies and describe three algorithms that can help terminology developers and users to identify potential mistakes. The methodology is based in part on linguistic criteria and in part on logical and ontological principles governing sound classifications. We conclude by outlining the results of applying the methodology in the form of a taxonomy different types of errors and potential errors detected in SNOMED-CT

Exploring evidence-based practice by occupational therapists when working with people with apraxia

Short Report Evidence in the literature supports a number of interventions that occupational therapists may utilise when working with people with apraxia, although there is no gold standard approach. A large-scale survey (n = 304, 36% response rate) was conducted with the membership of the College of Occupational Therapists Specialist Section – Neurological Practice to explore therapists’ understanding of apraxia and to provide a benchmark of current practice. Consensus was found in the majority of belief statements regarding the condition, although the respondents were unclear about the relationship between cognition and apraxia. When the therapists were asked to indicate their choice and use of interventions for apraxia, the results showed that the main consideration was the context in which a person performs activities, with moderate use of specific techniques including errorless learning and chaining. The results are related to the evidence base and the implications for occupational therapy practice and education are discussed

Structured computer-based training in the interpretation of neuroradiological images

Computer-based systems may be able to address a recognised need throughout the medical profession for a more structured approach to training. We describe a combined training system for neuroradiology, the MR Tutor that differs from previous approaches to computer-assisted training in radiology in that it provides case-based tuition whereby the system and user communicate in terms of a well-founded Image Description Language. The system implements a novel method of visualisation and interaction with a library of fully described cases utilising statistical models of similarity, typicality and disease categorisation of cases. We describe the rationale, knowledge representation and design of the system, and provide a formative evaluation of its usability and effectiveness

The big questions of personality psychology: Defining common pursuits of the discipline

Big questions of personality are those that are simple, important, and often have been asked repeatedly over time, such as “Who am I?” “What is human nature?” and “How does personality work?” This article identifies 20 big questions relevant to personality psychology. The historical background of each question is briefly described, and the questions are arranged into a model of big questions about personality. The questions, it is argued, both reflect and help to clarify the intrinsic interest in studying personality psychology. They offer insight into the cohesive nature of the field of personality by helping to define its common pursuits

Overgeneral Memory in Depression

This work is a phenomenological exploration of overgeneral memory in depressed patients. It reviews the current philosophical literature on the first-person experience of depression, which has so far omitted the phenomenon of overgeneral memory. However, this phenomenon is well documented within psychology; and this essay will show that its symptomatic appearance in depression and subsequent disturbance of self- experience justifies attention to the phenomenon within the phenomenology of depression. Both the theory of embodiment and the extended mind thesis work extensively with the nature of memory in other conditions such as Alzheimer's and dementia. Thus, these philosophical approaches will be utilised in an analysis of overgeneral memory; this will enrich the philosophy of depression, memory and self and highlight the value of the concepts of embodiment and the extended mind. Moreover, this philosophical interrogation suggests a route toward therapeutic interventions to help patients suffering from overgeneral memory applying techniques from extended mind and cognition studies

Values ethics and legal ethics: the QLD and LETR recommendations 6, 7, 10, and 11

The LETR Report recommended increased attention to ethics and values and to critical thinking. These aims could be achieved jointly through teaching ethical thinking: not as theory but as part of developing the capacity for ethical conduct. Such a pedagogy has the potential to become a QLD signature pedagogy supporting "life-narratives" of students. The LETR Report recommends a review of the QLD emphasising legal values and ethics. Concern with values and ethics is linked to concern with professional conduct. Maintaining the law degree as a general or liberal qualification is also strongly desired. These potentially conflicting drivers generate ambivalence towards legal ethics as a subject for study, especially if legal ethics is perceived as teaching the professional codes. Resolution of this tension is achievable through recognising the potential role of ethical teaching as part of an identity apprenticeship. Developing ethical character is as much a liberal as a professional aim. Ethics teaching can play an integrative role in the QLD. Formation of student identity is a central part of Higher Education taking colouration from being situated in legal education. In this context teaching legal ethics becomes the use of a salient example for carrying out the broader project of developing ethical capacity
