In psychology, alogia (/ˌeɪˈloʊdʒɪə, əˈloʊdʒiə, əˈlɒdʒɪə, -dʒə/; from Greek ἀ-, "without", and λόγος, "speech" + New Latin -ia) is poor thinking inferred from speech and language usage.There may be a general lack of additional, unprompted content seen in normal speech, so replies to questions may be brief and concrete, with less spontaneous speech. This is termed poverty of speechor laconic speech. The amount of speech may be normal but conveys little information because it is vague, empty, stereotyped, overconcrete, overabstract, or repetitive. This is termed poverty of content or poverty of content of speech.Under Scale for the Assessment of Negative Symptoms used in clinical research, thought blocking is considered a part of alogia, and so is increased latency in response.
