The Gospels And Acts' Polymodal Resurrection Accounts Corroborated In The New Testament Letters

The comments about hearing, seeing, and touching in 1 John 1:1 aren't limited to resurrection appearances, but surely included them and included them prominently. The passage is about the Word of Life, a context in which including resurrection from the dead makes more sense than not including it. The author is writing as one among the "we" of apostolic eyewitnesses, in contrast to the "you" of his audience. The apostolic experience wasn't limited to witnessing the resurrected Christ, but did include witnessing him in that context (Acts 1:21-22, 1 Corinthians 9:1). It could be argued that the resurrection experiences only included the seeing mentioned in 1 John 1:1, not the hearing and touching, but that's a less likely interpretation for multiple reasons. It's more complicated, and it involves an unlikely scenario in which a witness like the letter's author would be so interested in hearing and touching for the large majority of Jesus' life, but not so interested or unable to obtain hearing and touching in the resurrection portion of Jesus' life. The simplest and best understanding of 1 John 1:1 is that the author is appealing to the apostolic polymodal interaction with Jesus throughout his life, including his resurrection appearances. Given the emphasis placed on witnessing Jesus' resurrection in particular in order to qualify as an apostle (Acts 10:40-41, 22:14-15, 1 Corinthians 9:1), it would go against the context of apostolicity to make the apostolic experience in 1 John 1:1 so much more limited in the resurrection context than in the pre-resurrection context. Notice, also, that even in a scenario in which the author happened to never get an opportunity to hear or touch Jesus in the resurrection context, the passage would still be another example of the witnesses' interest in such interactions with Jesus. Given the large number of resurrection appearances that were reported and how many people were involved (e.g., 1 Corinthians 15:5-8), it's highly unlikely that few or none of the hundreds of people involved attempted to interact with Jesus in the way described in 1 John 1:1 or that they kept trying and failing to do so without realizing they were hallucinating, imagining things, or whatever. And 1 John 1:1 is a "we" passage. So, the critic who wants to appeal to the possibility that the author himself happened to only think he saw the risen Jesus, without thinking he heard or touched him, still has to address the other resurrection witnesses included in the "we".

1 Timothy 5:18 is also relevant. For more about the likely reference to Luke's gospel as scripture in that passage, see here.
